When you first released Twilight in production, I downloaded it and it basically worked and would crash on occasion. Recently you pushed out an updated version which I upgraded to (4-5 days ago) and now the game always crashes within maybe 20 to 30 turns. I always play beginner, large galaxy with maybe 4-5 opponents. I have been playing everyone except humans and the game will crash as I mentioned. I'm not sure how to provide you the information you require. The crash appears to occur when to many actions try to take place at the same time. This never appeared to be a problem during beta testing for me, only since this was released to prod.
This is my system: Windows XP SP2, 1GigRAM, Centerno, 256 MB VRAM.
