JobGiver_WorkRoot throws exceptions with deconstruct, mod related?

[1000101]

I am posting this here because the bugs sub-forum is for unmodded reproducible bugs.  While this has happened to me on more than one colony, the game is modded and I can't explicitly reproduce this as I can't find the exact trigger for it.

Bad topic title in a way, hopefully I can elaborate:

When starting a new colony, everything works fine.  The game assigns deconstruct jobs and everything is good.  After "a while,"  I get exceptions with deconstruct orders.

Builder threw exception in WorkGiver Deconstruct: System.NullReferenceException: Object reference not set to an instance of an object

  at Verse.GenClosest.ClosestThing_Global (IntVec3 center, IEnumerable searchSet, Single maxDistance, System.Predicate`1 validator) [0x00000] in <filename unknown>:0

  at Verse.GenClosest.ClosestThingReachable (IntVec3 root, ThingRequest thingReq, PathMode pathMode, TraverseParms traverseParams, Single maxDistance, System.Predicate`1 validator, IEnumerable`1 customGlobalSearchSet, Int32 searchRegionsMax) [0x00000] in <filename unknown>:0

  at RimWorld.JobGiver_WorkRoot.TryGiveTerminalJob (Verse.Pawn pawn) [0x00000] in <filename unknown>:0

(Filename: C:/BuildAgent/work/d63dfc6385190b60/artifacts/StandalonePlayerGenerated/UnityEngineDebug.cpp Line: 49)

This exception is thrown when a deconstruct job is automatically assigned and when manually assigned, however; when assigned automatically, the exception is thrown and the pawn finds something else to do.  When manually assigned, the exception is thrown and the pawn completes the deconstruct job.  This means I can always manually deconstruct but at some point the game fails to assign the jobs automatically.

I have spent hours trying to reliably reproduce it.  I can not find a single mod I use which changes the deconstruct work giver nor can I link it to a specific action or sequence of actions.

Sorry for the lack of info about this.  Maybe someone else has encountered this and knows what I did wrong?

I have attached my ModsConfig.xml and output_log.txt.  I didn't upload world/save due to the the need of the (sans Core) entire mod directory to go with it (due to individual mod tweaking).

in this instance it probably best to just start removing groups of mods to narrow it down to 1. Th errors doesnt help in this instance. Strip back to core only and test, then start adding mods back in until it happens.

erp, if I knew what the trigger was I would have done exactly this.

Unfortunately this is going to be a long process...


Ah well, thanks for at least responding.

Could you give me save file? I will try to recover it.
Or try do it:
Open saved file and find 'Deconstruct'. You might found some missing value in xml structure. Then, delete that part then your saved file might be recoverd.

I'm not sure if the save file is corrupt, actually.  That could be a distinct possibility, I have added/updated mods mid game.  It just seems like an odd bug.

I have experience like your bug. If you added in mid game, it can be stored by fixing save file. Try it.

I 'm having the same problem. No one yet knew how to solve it?

I did get this error a while back when i was making guns ... .
From what i gethear in my simply theory of theroies, is that sometimes on colony creation, something goes bad when mods are loaded or checked and it saves with the colony. Becouse my other tries to reproduce that error failed with new colonies, only two colonies had that error and there was nothing they had in common, well maybe the map
