I'm getting some random MAFs in my current game, but it seems a bit different from the ones I was getting in Warlords. For one, it only happens when processing a turn and I do not get a mangled autosave file. I usually reboot and the game runs fine for awhile. In Warlords, I'd get MAFs while the game was either autosaving or if I manually saved late in the game.
(I've already enabled the /3GB switch and that's worked fine on other mods.)
Not sure what's causing this, though it is currently just a minor annoyance. Will have to see how it progresses or switch to a smaller map and see what happens.
