Sounds like a corrupt install.
doubt it, I've reinstalled the thing from complete scratch.
1) stability is the same for me, GOOD no crashes of any kind
wasnt just me, eets had the same problem.
2) you talking about random maps? havent seen that in any of the offical maps, though i havent tried them all yet.
obviously, premade maps dont have that issue.
3) true and they know about it, but not to serious a problem for a hotfix.
hopefully
4) use the autosave if the game drops for some reason.
autosave has apparently the same issue, again eets had an identicle problem.
