Not good at debugging, please help me understand how to fix issues!!

[sagefight]

 seems as if the last line regarding the "Cities.Quest.IsValidHome" is blocking a few random faction quests such as peace talks, which is disappointing and definitely would like to fix that.

If there's any more information needed aside from my debug log let me know

Here's a look at the debug log, the top is from when I think the peace talk incident was trying to occur, the other is just from an loading autosave on start up

Hi,
since the word "cities" are at the message, i would say it is a problem with RimCities.
I would ask the mod author at the mod topic/discussion about it.

Since you use hugslib, there is a green button "Share logs" at the log window, you should add that link. It provide some detailed info's like your modlist.
