In early versions of this mod some peoples game did crash during the colchis or cimmeria turn due to a hardcoded Rome 2 bug. It should be fixed now, and I have not had anyone report problems since these changes were made. If you are having end-turn crashes, make sure your mod is up to date. If they still happen, please report the last few log entries from log.txt in your Rome II folder. If you know how to open the mod in a pack file manager, then set the LogAll and LogErr variables to true and cause a crash first, so it logs what happened.
