The thing about it and run it again if you desire if only for curiosity, the first symbol corrupted almost every time has been the units completed symbol and it is tied to a lot of memory. Even if each unit completed "only" uses 5kb that amount of units would shove the memory usage up a meg by itself. The second one to corrupt has been costruction completed symbol for the same reason.
Now from a modder's perspective, in hard numbers, what are the maximum amount of units can be recruited per turn, maximum number of biuldings constructed? These are the kinds of things modders have control over if given the numbers. If anyone, including me wants to kick in the afterburners, then it's our fault. If we have no information, it's not our fault. Besides, I've had 6 besieged settlements before at one time. I lost 2 of them before I could get reinforcements there.
