This is just wierd.

I was playing a normal game in the middle ages, and I end my turn, it lags, then, all the colors smeared and the words turned into what looked like bar codes, this has probobly been reported but could you tell me about this bug?

sounds like a graphics card that is overheating/dying
is there louder than usual noise from the computer when this happens?
