The game crashes whenever I win, or after the last move of the game. Steam recognizes the achievements but as it is processing the last move it freezes and crashes. I have loaded the game right before the final move and I have had simlar results. Any help? 

I won again yesterday and it still crashed so it has been three full games with the same results. 

Any tech support?

Yup, still happens, but usually just in multiplayer games to me. Here is a link to what it looks like for instance, if you think devilweed is making stuff up, it happens in about 90% of my multiplayer games.

This has been happening to me. I tried reloading the game 3 or 4 times, reloaded steam, and still nothing works. It just freezes up and crashes when it's loading up my victory turn. 

i haven't tried it again lately but it is frustrating. everything i have tried hasn't worked either.
