I have looked at the previous post about this but I didn't find a resolution that worked for me. Thus, my question is this: how do I create new culture groups and move existing cultures into those groups without the game freezing at Adapting History? While I know that others have had the same problem, I also know that it is possible since two of my favorite mods, Lofmod and Epigoni Mod, both do so successfully. What could I possibly be doing wrong? Please let me know. I would like to create a mod that runs from not long after the founding of Rome through the conquests of Alexander the Great, but need to, at the very least, separate Egyptian and Numidian cultures and add a Mesopotamian Culture Group for this to work. If anyone can help me, please do so. I really appreciate it.
