Since I play a lot of sandbox games, I have to deal with a lot of popup issues. For example, in Red Faction: Guerilla, smokestacks and mountains tend to spontaneously appear out of nowhere. In Asssassin's Creed 1 & 2, the same thing could be said about tall buildings. This usually doesn't bother me, but when GIANT buildings just materialize out of nowhere, it's a little weird. Does it bother you?
