NullReferenceException

Message: Object reference not set to an instance of an object.

Source: SandBox

GetSuitableSpear - PrepareGuardAgentDataFromGarrison - TakeGuardAgentFromGarrisonTroopList - CreateStandGuardWithSpear

I'm getting this crash whenever I take a settlement with my custom culture and try to go to Lord's hall or dungeon
REASON: Custom culture guards entries in spgenericcharacters.xml (sandbox folder) need to go in spnpcharacters.xml in your mod's folder

Source: TaleWorlds.CampaignSystem

CampaignObjectManager - InitializeCachedData - InitializeOnNewGame - OnInitialize - DoLoadingForGameType

REASON: Settlement bound="Settlement.town_CR4" pointed to the non-existing settlement in settlements.xml

GetHeroesForEffectiveRelation - ApplyInternal - CreateRebelPartyAndClan - StartRebellionEvent - DailyTickSettlement

REASON: ?

BuildWorkshopForHeroAtGameStart - BuildWorkshopsAtGameStart - OnNewGameCreatedPartialFollowUp

REASON: Used non-existant equipment set for NPCCharacter: <EquipmentSet id="npc_gentry_equipment_sturgia"/>

GetBodyProperties - GetCharacterCode - set_Character - set_Troop - PartyCharacterVM - InitializePartyList

REASON: Used non-existant BodyProperty for NPCCharacter

DefaultMapDistanceModel - GetDistance

REASON1: Wrongly assigned Settlement, Kingdom without a settlement. Attach dnSpy, it will show faction.FactionMidSettlement == null. Fix your XML.

REASON2: Problems with Navmesh. Inaccessible settlements. Old/mismatching settlements_distance_cache.bin - fix navmesh, regenerate settlements_distance_cache.bin

Once I loaded Lemmy's map together with mine and got this crash ¯\_(ツ)_/¯

CampaignObjectManager.InitializeCachedData()

REASON: settlements.xml error - I accidently deleted one settlement and village had no bounded castle (crash on settlement.OwnerClan.OnBoundVillageAdded(settlement.Village);). This was on new game start.

If nothing helps, use this patch:

[HarmonyPatch(typeof(DefaultMapDistanceModel))]
[HarmonyPatch("GetDistance")]
[HarmonyPatch(new Type[] { typeof(Settlement), typeof(Settlement) })]
public class DefaultMapDistanceModel_GetDistance_Patch
{
    static bool Prefix(Settlement fromSettlement, Settlement toSettlement, ref float __result)
    {
        if (fromSettlement == null || toSettlement == null)
        {
            __result = 0f;
            return false;
        }
        return true;
    }
}

DefaultMapDistanceModel - GetDistance - VillageGoodProductionCampaignBehavior - DistributeInitialItemsToTowns - OnNewGameCreatedPartialFollowUp

REASON: it happens when a village is too far away from a city (even if the village belongs to a castle) but there is a script to fix that
SOLUTION: : The problem solved by having to make a town closer to the castle, and raise the trade bound system to 4000 (more info)

SpawnNotablesIfNeeded - NotablesCampaignBehavior - DailyTickSettlement

REASON: Some type of notable is missing for some culture. I was missing RuralNotable
Set in <notable_and_wanderer_templates> in culture XML

CalculateAverageWage - DoLoadingForGameType - DoLoadingForGameManager

REASON: ??? (maybe something related to party templates with non-existant troop IDs, but not confirmed)

CharacterObject - GetSkillValue - DefaultPartyMoraleModel - GetMoraleEffectsFromSkill - GetEffectivePartyMorale

REASON: used not existant troop ID in the <MBPartyTemplate id="villager_CUSTOM_CULTURE_template">
HINT: Check Encyclopedia-Troops if necessary troop is actually in the game.

DefaultPartyWageModel - GetTotalWage - MobileParty - get_TotalWage - get_LimitedPartySize - CalculateGarrisonChangeInternal

REASON: Troop ID used in partyTemplates.xml refers to a non-existing troop ID in the trooptree.

SetInitialValuesFromCharacter - CreateNewHero - CreateSpecialHero - CreateMinorFactionHeroFromTemplate - SpawnMinorFactionHeroes - OnNewGameCreated

REASON1: spclans.xslt and custom_spclans.xml were in a separate folder for spclans, but missing empty spclans.xml file
REASON2: for Lord NPCCharacter used EquipmentSet instead of EquipmentRoster

HeroCreator - CreateNewHero - CreateSpecialHero - CreateMinorFactionHeroFromTemplate - SpawnMinorFactionHeroes - OnNewGameCreated

REASON: error in <minor_faction_character_templates>, I used name= instead of id=

HeroCreator - CreateNewHero - FindRandomInternal - CreateNewHero - CreateSpecialHero

REASON: error in XSLT by assigning a culture to a hero

SiegeTowerSpawner - AssignParameters - SpawnerEntityMissionHelper - OnPreInit

On starting the scene.
REASON: name property for siege_tower entity:

<game_entity name="siege_tower_5m_spawner_right" prefab="siege_tower_5m_spawner">

removed name=... solved the crash:

<game_entity prefab="siege_tower_5m_spawner">

ArrangeDestructedMeshes - SetUpScene - AfterStart - FinishMissionLoading

REASON: siege engine can't find which wall segment to attack. Tag is missing. Commented out in xscene:

<game_entity name="easteurope_wall_level_l1_right" old_prefab_name="">
    <flags>
        <flag name="record_to_scene_replay" value="true"/>
    </flags>
    <tags>
        <tag name="right_wall"/>  <--- this was used by siege_engine >
    </tags>
    ...

DestructableComponent - OnInit

The scene was working on L1 Summer/Winter/Sprint, crashing on L1/Fall and on all L2/L3
REASON: entity with DestructableComponent had debris_holder with season_mask="253". Removing the season_mask solved the crash:

<!-- <game_entity name="debris_holder" old_prefab_name="" mobility="1" season_mask="253"> FALL CRASH -->
<game_entity name="debris_holder" old_prefab_name="" mobility="1"> <!-- NO CRASH -->

BackstoryCampaignBehavior - OnNewGameCreated

REASON: commented out some native hard-coded lord/settlement
Check in BackstoryCampaignBehavior.OnNewGameCreated
Fix with Harmony to skip this native code:

[HarmonyPatch(typeof(BackstoryCampaignBehavior))]
[HarmonyPatch("OnNewGameCreated")]
public class BackstoryCampaignBehavior_OnNewGameCreated_Patch
{
    public static bool Prefix()
    {
        return false;
    }
}

InitialChildGenerationCampaignBehavior - OnNewGameCreatedPartialFollowUp - InvokeList - OnNewGameCreated

REASON: Missing male or female lord of one of the cultures. Both male and female lords should be present for each culture to pass this function at the game creation.

CreateNewHero - CreateSpecialHero - OnNewGameCreatedPartialFollowUp - InitialChildGenerationCampaignBehavior

REASON: Hero present, lord not present, lord used in a clan definition as owner
REASON2: wrong id in <xsl:template match="Settlement[@id='village_EN1_3']/@culture">

DefaultMapDistanceModel - GetDistance - UpdateFriendshipAndEnemies

REASON 1: Lord/hero without a proper clan (clan not created/deleted)

REASON 2: Incorrect load order when launching game, e.g. Lemmy's map was loaded after a mod using it.

Kingdom - OnNewGameCreated - InvokeList - OnNewGameCreated

REASON: Deleted hero/lord, the 'owner' of the Kingdom

CalculateDailyProductionAmount - GetWerehouseCapacity - TickProductions - OnNewGameCreatedPartialFollowUp

REASON: assigned a settlement to non-existant clan
REASON2: error in defining minor_clan, I had label_color="FF7264D16" (one digit too much in the color code)
REASON3: error in defining a clan, had NaN in banner_key="11.141.19.1836.1836.768.788.1.0.NaN.510...., wrong/duplicate Faction id=

NameGenerator - CalculateNameScore - SelectNameIndex - GenerateHeroFirstName - CreateSpecialHero - InitialChildGenerationCampaignBehavior - OnNewGameCreatedPartialFollowUp

REASON: Clan's owner was non-existant Lord

DefaultMapDistanceModel - GetClosestSettlementForNavigationMesh - GetDistance - FindNearestSettlement - TryToAssignTradeBoundForVillage - UpdateTradeBounds

REASON: saved a Main_map when game was open, xscene file gone, map gone. Game started with vanilla Main_map with custom settlements.xml

AgingCampaignBehavior - OnHeroComesOfAge - InvokeList - DailyTickHero

REASON: error/missing sandboxcore_equipment_sets.xml for the hero's culture. Hero turned 18

TournamentGames - TournamentMatch - AddParticipant - TournamentBehavior - FillParticipants

REASON: RBM Tournament expects local culture troops in the settlement for the Tournament. Troops were not implemented for that culture.

Clan - OnFortificationAdded - PreAfterLoad

REASON: Old save loaded on a new map with new settlements not present in the old save

GangLeaderNeedsToOffloadStolenGoodsIssueBehavior - ConditionsHold - OnCheckForIssue - IssuesCampaignBehavior - CreateAnIssueForSettlementNotables

REASON: It's seems it is related to the mission NotableWantsDaughterFound. When it ends the GangLeader is spawned in the village where this mission was originated. This GangLeader then is used for this OffloadStolenGoods mission check and that results in the crash. Seems like native bug. I patched the crashing method with the check if village notable is not GangLeader.

ApplySimulatedHitRewardToSelectedTroop - SimulateSingleHit - SimulateBattleForRound

Crash in CharacterObject.get_FirstBattleEquipment
REASON: troop with all <EquipmentRoster civilian="true">, without <EquipmentRoster>

Source: MonoMod.Utils

GauntletMovie - LoadMovie_Patch0 - Load - LoadMovie

REASON: Movie XML file not present. (deleted/wrong name/path?)

LordConversationsCampaignBehavior - conversation_wanderer_introduction_on_condition - RunCondition

REASON: No native settlement town_ES4 in the game.

GetEffectiveDailyExperience - DefaultPartyTrainingModel - OnDailyTickParty

REASON: melee_elite_militia_troop in culture.xml was set to non-existant troop ID

ArgumentNullException

Message: Value cannot be null. Parameter name: source
Source: System.Core

CreateHeroAtOccupation

REASON: in CUSTOM_culture.xml commented out one name:

<male_names>
    <!-- <name name="Adalbert" /> -->
    <name name="Adalbern" />

also commented out one basic_mercenary_troops:

<basic_mercenary_troops>
    <template name="NPCCharacter.eastern_mercenary" />
    <template name="NPCCharacter.western_mercenary" />
    <!--<template name="NPCCharacter.sword_sisters_sister_t3" /> -->
</basic_mercenary_troops>

SortedList.Add - AiVisitSettlementBehavior - FindSettlementsToVisitWithDistances - AiHourlyTick

Message: An entry with the same key already exists
REASON: had <Village> with the same id in the settlements.xml (not Settlement id but Village id with the _comp_!)

Simple bash script to check for 'Village id' duplicates:

#!/bin/bash

# Define the XML file path
XML_FILE="settlements.xml"

# Check if the file exists
if [[ ! -f "$XML_FILE" ]]; then
    echo "File $XML_FILE does not exist."
    exit 1
fi

# Extract id attributes from Village elements
ids=$(xmllint --xpath '//Village/@id' "$XML_FILE" 2>/dev/null | grep -o 'id="[^"]*"' | sed 's/id=//g' | tr -d '"')

# Check if xmllint failed
if [[ $? -ne 0 ]]; then
    echo "Error processing the XML file."
    exit 1
fi

# Find duplicate ids
duplicate_ids=$(echo "$ids" | sort | uniq -d)

# Display the duplicate ids
if [[ -n "$duplicate_ids" ]]; then
    echo "Duplicate Village ids found:"
    for id in $duplicate_ids; do
        count=$(echo "$ids" | grep -c "^$id$")
        echo "id: $id, Count: $count"
    done
else
    echo "No duplicate Village ids found."
fi

Linq.Enumerable.Any - Extensions.IsEmpty - NameGenerator - GetNameListForCulture - GenerateHeroFirstName

REASON: error in the culture xml file

InvalidOperationException

Message: The XmlReader state should be Interactive.

- CUSTOM_settlements.xml completely empty
- etc

Message: Sequence contains no matching element
Source: System.Core

Enumerable.First - InitializeCaravanOnCreation - CreateCaravanParty - CreateParty - CreateCaravanParty

REASON: CUSTOM_culture notable Merchant was expecting CaravanGuard with the same culture: character.Culture == mobileParty.Party.Owner.Culture

InitializeCaravanOnCreation
CharacterObject characterObject = CharacterObject.All.First((CharacterObject character) => character.Occupation == Occupation.CaravanGuard && character.IsInfantry && character.Level == 26 && character.Culture == mobileParty.Party.Owner.Culture);

Single - CharacterCreationCultureStageVM - SortCultureList - CharacterCreationCultureStageView

REASON: Native culture is removed or is made is_main_culture=true

IndexOutOfRangeException

Message: Index was outside the bounds of the array.
Source: TaleWorlds.CampaignSystem

DefaultMapWeatherModel - GetWeatherEventInPosition - WeatherAudioTick - TickVisuals

Usually crash when going to the very edge of the map.

REASON: Marked 'Use Dynamic Weather Effects' without the a flowmap.
OTHER REASONS: Maybe map is not a square. Maybe flowmap is not 1024x1024.

If nothing helps, use this patch:

[HarmonyPatch(typeof(DefaultMapWeatherModel), "GetWeatherEventInPosition")]
public class DefaultMapWeatherModel_GetWeatherEventInPosition_Patch
{
    // Create a field reference for accessing the private _weatherDataCache field in DefaultMapWeatherModel
    private static readonly AccessTools.FieldRef<DefaultMapWeatherModel, MapWeatherModel.WeatherEvent[]> _weatherDataCacheRef =
        AccessTools.FieldRefAccess<DefaultMapWeatherModel, MapWeatherModel.WeatherEvent[]>("_weatherDataCache");

    static bool Prefix(Vec2 pos, ref MapWeatherModel.WeatherEvent __result, DefaultMapWeatherModel __instance)
    {
        // Define the variables that will be passed as out parameters
        int num, num2;

        // Use AccessTools to get the private method GetNodePositionForWeather
        MethodInfo getNodePositionMethod = AccessTools.Method(typeof(DefaultMapWeatherModel), "GetNodePositionForWeather");

        // Prepare the arguments for the method (since it's expecting out params, you should use a reference array)
        object[] methodArgs = new object[] { pos, null, null };

        // Invoke the method using reflection
        getNodePositionMethod.Invoke(__instance, methodArgs);

        // Extract the results from the out parameters
        num = (int)methodArgs[1];
        num2 = (int)methodArgs[2];

        // Calculate the index
        int index = num2 * 32 + num;

        // Access the private _weatherDataCache field using the field reference
        var weatherDataCache = _weatherDataCacheRef(__instance);

        // Check if the index is out of bounds
        if (index >= weatherDataCache.Length || index < 0) // Use array length for safety
        {
            // Return WeatherEvent.Clear and skip the original method
            __result = MapWeatherModel.WeatherEvent.Clear;
            return false;
        }

        // Otherwise, return the cached weather data and skip the original method
        __result = weatherDataCache[index];
        return false;
    }
}

MapScene - GetNavigationMeshCenterPosition - DefaultMapDistanceModel - GetClosestSettlementForNavigationMesh - GetDistance - CalculatePartyInfluenceCost - CalculateTotalInfluenceCost

REASON: settlement not covered by Navmesh
REASON2: hole in the Navmesh
REASON3: outdated Settlements Distance Cache. Delete/regenerate it

hunharibo: looks like a navmesh issue. Either a face with inverted normals or a concave quad or a face that is not connected to anything

FinalizeMission - EndMissionInternal - CheckMissionEnd - OnTick

Crash was on the exit out from the mission.
REASON: xscene contained one entity, and commenting it out stopped the crash, no idea why/how, there are more similar entities in the scene:

<game_entity name="aserai_grandbazaar_wall" old_prefab_name="" occlusion_body_name="bo_occ_aserai_grandbazaar_wall">
    <transform position="-73.488, 137.875, 0.924" rotation_euler="0.000, 0.000, 1.571" scale="0.470, 0.150, 0.000"/>
