The seasonal camps are not working properly I think. I can not build mines or anything else so I can not get access to resources right away. Every improvement I build automatically turns into a seasonal camp, and then it tells I have to wait 38 turns before it will turn into the appropriate improvement to unlock resource. Having to wait 38 turns to get my resources is not fair. Using latest SVN, guess I will have to revert to before the seasonal camps were added.
