WeaponsTab_EquipLoadout.thinkRoot can be null
I keep getting this red error here:

Exception in Verse.AI.ThinkNode_Priority TryIssueJobPackage: System.NullReferenceException: Object reference not set to an instance of an object at (wrapper dynamic-method) Verse.AI.ThinkNode_SubtreesByTag.Verse.AI.ThinkNode_SubtreesByTag.TryIssueJobPackage_Patch1(Verse.AI.ThinkNode_SubtreesByTag,Verse.Pawn,Verse.AI.JobIssueParams) at Verse.AI.ThinkNode_Priority.TryIssueJobPackage (Verse.Pawn pawn, Verse.AI.JobIssueParams jobParams) [0x00022] in <c36f9493c9844ddaa7fb5c788416098f>:0 Verse.Log:Verse.Log.Error_Patch2(String, Boolean) Verse.AI.ThinkNode_Priority:TryIssueJobPackage(Pawn, JobIssueParams) Verse.AI.Pawn_JobTracker:Verse.AI.Pawn_JobTracker.DetermineNextJob_Patch4(Pawn_JobTracker, ThinkTreeDef&) Verse.AI.Pawn_JobTracker:TryFindAndStartJob() Verse.AI.Pawn_JobTracker:Verse.AI.Pawn_JobTracker.EndCurrentJob_Patch2(Pawn_JobTracker, JobCondition, Boolean, Boolean) Verse.AI.Pawn_JobTracker:JobTrackerTick() Verse.Pawn:Verse.Pawn.Tick_Patch4(Pawn) Verse.TickList:Tick() Verse.TickManager:Verse.TickManager.DoSingleTick_Patch2(TickManager) Verse.TickManager:TickManagerUpdate() Verse.Game:UpdatePlay() Verse.Root_Play:Verse.Root_Play.Update_Patch1(Root_Play)

I was able to track down the crash because of a null thinkRoot here, which Verse.AI.ThinkNode_SubtreesByTag does not like. It assumes thinkRoot always exists. Here's my debug info:

ThinkNode_SubtreesByTag - found null thinkRoot: this=Verse.AI.ThinkNode_SubtreesByTag, pawn=Manabu, ThinkTreeDef=WeaponsTab_EquipLoadout

I also get the same GUI error that somebody else reported:
