Some enemies spawned outside the bastille of might located in the upper middle of F5 on the map grid in Hallowed Moor

Some of the enemies during the last wave of the encounter spawned outside the bastille of might building that gets sealed up once the encounter starts. Its the one located in the upper middle of F5 on the map grid in Hallowed Moor. I was able to use shockwave to kill them through the door as they ended up grouping around there but without some sort of AOE damage i dont think i could have beat it. The only reason i realized they were out there was because me companion was swinging at the door and hit them a few times before they were no longer able to hit them with their axepick. Thus why i labed it as unable to play, since you could get stuck in there otherwise.
