Untargetable and invulnarable mobs in temple won't let me complete room

Bug Report ID: #3795356373

2 or 3 Quadrilla monkeys got stuck on some terrain or a door or something in the vaal temple. They got out of it, but they turned untargetable and invulnerable. They still followed me around, but neither I, nor my wolves could attack them. Mousing over them didn't even show anything.

This got me stuck in the next room, as it wouldn't register the room as completed with the monkeys alive.

But, while writing this bug report, I made sure to check that I hadn't missed a monster, and somehow a monster from another room jumped in through the closed door, and suddenly I could target and kill the monkeys and complete the room.

So while I got the room completed, I'll still leave this bug report, as the untargetable monkeys not letting me complete a room was still a thing.

edit - You're right that they're escaping from another room while the door is shut and are un-targetable like you said.

If the room they came from isn't beside it I had to back out go to the room they came from and clear that room then was able to target it in the room it had clipped through to
