Anybody else have this problem? After taking over about 25% of any map with the undead faction all game loads take about 10x longer than any other faction.

I think it has something to do with the extra doodads like dead trees and stuff on ground that appear when you expand out with them. I also take a FPS hit during regular gameplay.

Every other faction seems fine. i got 100 hours of playtime and only have this problem with undead.
