In some of the rooms the crawlers get stuck.
One room with lots of hanging bodies, crawlers get stuck behind a wall outside the map
Also, the room with the spiral staircase, crawlers get stuck high up above that staircase.
Fix for now - If you wait around the outside edge of the staircase the crawlers eventually spawn back into the map
