I was playing wood elves Mortal empires with SFO mod and others submods. Once I got to turn 30, my save game files get corrupted and game crashes when I am on TURN phase and some Skaven clan makes it's turn.

The last thing in the vandy_lib_log is saying this:
[mct_settings] <1.9s> Read only: false
[mct] <1.9s> set_log_file_path() called for mct_mod with key [mixu_LL2], but no file with the name [mixu_log.txt] exists on disk!
[mct_ui] <17.9s> UI created!
[pr_ui] <42.9s> init
[! ERR !] <43.3s> SCRIPT ERROR
Trying to get mod with name [confederation_options] but none is found! Returning nil.
