So..: i bought the game and noticed immediately some weird things happening. 

1st. Starting the game with many custom races in the game and with insane maps make the game crash as soon as you try to create a map. No error message. The game just close itself without error messages. This happens with both mods activated, with only the dlc activated or with no mod enables.

2nd. If I limit the number of races in the game and reduce the map size (But mostly if i reduce the number of races) the game start. Run turns correctly until unexpectedly it crashes with no error message.

When I try to load the last game it loads correctly, does more turns and again crashes. The number and intensity of crashes raise the more the game goes on...

I am unable to identify if this is a Custom races (Downloaded from the workshop of steam) or something else. Please give me indications on how to identify the problem. I have a very powerful Windows 7 x64 O.S. with 12 mega RAM and 2 Mega dedicated video card. It should more than enough to run the game at high standards...

The game should not crash at all... Why does this happens?
