I've tried her in Brutal Wolfenstein (yeah, weird cross-over) and some mazes there seem to get her out of bounds, between the corridors (I think, judging by the glowing through the walls). And that's where I sometimes get her stuck at starting points if there's a wall aside from the player.
Those are minor troubles TBH, since she seems to get out easily enough. Real problem is pillars in that mod that she attacks relentlessly, but since some of them can't be destroyed she won't leave them alone and I have to run on the other end of the map, hoping me fighting enemies will bring her back. It actually happens with other follower mod I've tried, I believe that's just how followers work.
And yes, I do have a blast.
