Checked inside. was not an object as originally thought. client side? dont want to crash the server by going back if thats a thing but ill take you there jorb if u need to inspect it.
This is a fairly common bug at the moment. The devs are aware of it and it has been reported multiple times now. It's strictly a graphical glitch so I don't think you can crash the server with it. =) Reloading the area or restarting your client should fix it.
