Hello!

Your mod "Vanilla Factions Expanded – Empire" is trying to call a method (QuestGen_Misc.DropPods) that no longer exists or has changed in RimWorld 1.6. Or... the "Vanilla Expanded Framework" mod which itself might be outdated.

Error in Vanilla Factions Expanded - Empire, assembly name: VFEEmpire, method: <>c__DisplayClass0_0:<RunInt>b__0, exception: System.MissingMethodException: Method not found: RimWorld.QuestPart_DropPods RimWorld.QuestGen.QuestGen_Misc.DropPods(RimWorld.Quest,RimWorld.Planet.MapParent,System.Collections.Generic.IEnumerable`1<Verse.Thing>,string,Verse.Grammar.RulePack,string,Verse.Grammar.RulePack,System.Nullable`1<bool>,bool,bool,bool,string,System.Collections.Generic.IEnumerable`1<Verse.Thing>,RimWorld.QuestPart/SignalListenMode,System.Nullable`1<Verse.IntVec3>,bool,bool,bool,RimWorld.Faction)
