Galciv 3 is crashing frequently after the 1.71 build. I was about 3/4 of the way through the Terran campaign and the save game crashes on the next turn when the Altarians attack one of my starbases. So I went back to the Arcean campaign, finished the first tier, playing the second, and it crashes again whenever I try to modify a shipyard build. If I don't do this, it seems to be OK. Has anyone actually completed a campaign without crashes? I've played several games on earlier builds without crash problems.

I've verified my Steam cache several times but it doesn't seem to help.
