Sliced bread is severely overrated.

Seriously, it has probably something to do with system memory and processor capacity limitations. I'm running a top end Core 2 Duo system with nearly the latest kit as of last September and turn resolution can take a frighteningly long time in e.g. 8 nation Cradle games. Haven't had problems with the masses of units, but my old machine (a Y2K vintage Celeron 500 system that burned out in July) would have simply collapsed under this sort of load. It'd be nice to know the hardware specs of the people who are experiencing this bug issue, it could help narrow it down.
