Oh, REALLY! Well, I haven't had any crashes so far, and I did no patching of vanilla civ before I installed C3C.
Actually, all I wanted to do was compare resource levels in vanilla with C3C. I'm having a very hard time getting a hold of anything in some games. If you can't get the stuff to build RR, even thru generous trade, because there just isn't enough to go around, that's not really my idea of fun. I think I will make at least iron and coal more readily available.
