Nah, the sandbox map its not working when started by Zero-k lobby, so i believe this is not related to AI and i just started a multiplayer match as test (and locked to not let anyone in, and it still crashed).
edit: so far everything works normally when i use the springlobby, chicken defense, sandbox with null ai, single player with CAI bots and multiplayer, but if spring its started by Zero-K lobby, its CTD and a message that spring.exe stopped working.
edit 2: Oh and and i forgot to post this:
i use Windows 7 64 bits ultimate
a Sandy Bridge Core I5 2.3 ghz
A intel Graphics 3000 HD as videocard (its working good, the only performace issue i get its when i have way too many units in the screen)
and 4 gb ram
edit 3: This was happening on 1.0.3.2 and it stills happens on 1.0.3.3 so i dont think it was an update bug.
