## Description of the bug
i tried to passively grab a lurker corpse (normal lurker, no strain) off the dropship after it was fultoned but when i tried to move with my grab, it always broke, even if i put the lurker on a roller bed

## What's the difference with what should have happened?
i should be able to move the dead lurker

## How do we reproduce this bug?
1) fulton a lurker
2) have the fulton picked up
3) try to grab it off the fulton on the normandy
4) move a tile while grabbing
5) grab breaks

- Note: This specific xeno is indeed not movable. Reportedly someone figured out they could move it by dragging it onto a table. The xeno is not anchored. Teleporting it through VV does not unstuck it. 'Throwing' it with build mode does not unstuck it. Reviving and killing it, does not unstuck it. Reviving and controlling it, does not unstuck it. There is a runtime for the specific xeno, but I am unsure if it is related. The mob does not seem deleted.
