Ok, weird, I've succeeded in going to the next turn without having the game crash. I usually load the mod using a shortcut where it "targets" the mod folder, so the first time the game crashed, I assumed that that wasn't relevant to the issue. Since I assumed that the shortcut target wasn't relevant, when I reloaded the save and ended the turn and crashed multiple times, I was loading the game normally, with the usual .exe, not with the shortcut target. Then I tried by loading the game with the shortcut target, and this time, I was able to go to the next turn. I had assumed that the first time that the crash happened that I had loaded the game that time with the shortcut target, but perhaps I hadn't? Strange... anyway, for now, it looks like it's ok. The screwy font, though, is still happening.
