Mob models loading in zones they shouldn't

As you can see here, the rhoas are about to stage an invasion of my hideout. (They don't actually move or anything, they're just posed weird.)

My guess is that this is some sort of client bug that occurs after heavy graphics load causes the sort of stalling that Blight has been inducing - it also happened after I dealt with a particularly tanky group of mobs on an EoW build with a very high hitrate. Not sure how the presence of these models proliferated into my hideout, but I do find their presence comedically endearing.
