I dont know if everyone's figured this out already, but I just did, so I thought I'd post it.

I suffered from this CTD in my 0.8 Romani campaign until I tried the fix suggested by MarcusAureliusAntoninus and Teleklos Archelaou. Like Randarkmaan i couldn't get it to work with pantodapoi so I tried another unit:

recruit "germanic infantry frankamannoz slave" 0
and it worked perfectly, my game no longer CTDs on rebels turn. So thanks for the help everyone, and I hope I've been of some assistance!
