Need to refresh game after every attack

I'm having the same problem on Tib 31 and Wrath 11 although worse on Wrath 11. After each attack, whether a base or a camp, I need to log out and log back in again to visit base and repair. Cant do multiple attacks without game freezing up. Screen goes dark and just cycles after attack complete without returning to attack formation. I have cleaned cache, etc. Does not fix problem. Has been going on for a couple of weeks now.
