## Description of the bug
If you close a door gun, or pick it up with a loader, it collapses with the person using it, and teleports them somewhere.

## What's the difference with what should have happened?
Don't teleport people when the door gun gets closed on them.

## How do we reproduce this bug?
1: Put a door gun on the inside of the Alamo
2:Close/Collapse it, or use a loader on it.
3:The person is now gone, and I have to teleport them out, even if the gun is un-collapsed.
