Played on Medium map... Finally got a map that would let me get to over 150 turns without freezing up or crashing. But then I crashed haha. I came back loaded the game and was good to go again... It started slowing down while trying to move my camera around the map. Seemed like alot of lag and then as I was trying to load The Battle Viewer. No viewer came up and it crashed out. Seems like there is a massive memory problem from what I can tell. I dunno though. I am not the expert 
Oh A screen came up and said a texture wouldn't load but it wouldn't let me copy so I am unable to tell you which texture.
Question. When we crash and its saying its not responding... Is it still sending the data on the crash to you guys? Or what if we hit alt F4... I wish there was something that let me know for sure if you guys got the crash information. I want this game to be epic. And I really want to make it past a maximum of 200 turns even if I have to play a small map.
