When dropping off the ledge it opens and you can see where the mob glitched through the wall trying to attack from below and got stuck inside that part of the map.
I don’t have time to upload the other files. But the screenshot should show what is needed for whatever that map is inside crucible.
Just this screenshot is enough 
Appreciate it ManicReaper.

I had three of those cerim enemies get stuck under that rock formation right after I entered the floor and moved towards them, the first one managed to get out, the second one only had his head poking out, and the third one got stuck under there for good
if you don’t have some kind of long range melee weapon or aoe attack to hit him through the wall that’d be a nasty softlock
