I posted this on Steam but still can't find the answer. I have about 40 mods and my last game with 38 or so had no problems (other than late game battle lag). I added a few mods, started a new game and after about 15-20 hours, I have problems where some minors won't mine. They just wander even though the priority is set to 1 and others are unchecked, area is unrestricted, etc. One guy I banished for this and he wandered around in the winter in sub-zero weather. I felt bad, so I made him a prisoner for the winter.

Today I am getting these additional errors.
(In red) Null key while loading dictionary of Verse.Pawn and WorkTab.PawnPriorityTracker. label=Priorities
(skipped some non red or yellow lines)
(yellow) Could not resolve reference to object with loadID Thing_Human613145 of type Verse.Pawn. Was it compressed away, destroyed, had no ID number, or not saved/loaded right? curParent=WorkTab.PawnPriorityTracker curPathRelToParent=

(yellow) Failed to spawn item pork
(red) RimWorld.WorkGiver_DoBill provided target Thing_ElectricStove134922 but yielded no actual job for pawn MMoses. The CanGiveJob and JobOnX methods may not be synchronized.
Seems to not like pork or cooking it... Is the game on a kosher diet?
I guess one option is to remove the new mods, but if I could find the conflicting one(s) that would be ideal so I can let the author(s) know. If I knew how to find a simple list of the mods and copy them, I would if that would help.
I am a noob at troubleshooting this language.
Any help or ideas would be greatly appreciated.

It seems I need gold but I can't find it on the map I am on.
