I played a few games to test some modding, I don't seem to have a problem. They're not focusing on minors in Crusade, they found a way to utilise as many major Civs as you want apparently(well, within reason, I think 100 has been mentioned) so dunno if it will be fixed if it's a bug. Sounds a strange bug if it is, though.
Like Murphy's Law, or synchronicity, or both.
