I've noticed that when reinstalling a billiards table, you can't move it into a space that would have standable space on all sides, but for the billiards table presently being in that spot. It should let you move it there, because once they table is uninstalled, there will be nothing in the way.
To make it clearer, here's a picture:

As you can see, the intended spot would have standable space on all sides, but for the table currently being there. I think this is a bug, or at least a flaw that should be corrected.
It makes perfect sense, and happens to work with anything that is able to be reinstalled. Able to be reproduced easily enough, but I'm not sure it qualifies as a bug. An oversight? Maybe. Easy to work around for now; uninstall, and then reinstall.
Bug confirmed. I have listed it on Mantis here: https://ludeon.com/mantis/view.php?id=2647 Thank-you for reporting this.
