So, strange thing. I'd long ago modded the Casse general bodyguard to use the druid units instead of chariots and started a new game. I've been playing this game for literally years, I think I started it in 2009 or so.
Just a few days ago I noticed that somehow my Casse bodyguards have picked up chariots again (not exactly sure how), so I edited them back to druids. Now whenever I adopt a new general his bodyguard is Libyan calvaly, Meqpeqed Libi or something similar.
I have saves going back ages so I can revert to an earlier save, but is there any way to keep this from happening?
