well crashes / bugs usually always occur after battles - not at/directly after the battle, but some time afterwards - most of the time after i attacked/killed another sovereign or their units / cities...
i will try reporting some in the near future
Yeah, otherwise how will they figure out how to fix the bugs without providing them the information
Go to a save from before this bug hit you, play til it occurs, then provide the memory dump and your dxdiag info, and maybe even a save taken just before the bug. As Sushikawa said this is a real beta, not a demo-in-beta-clothing
