Door Placing Fails on Realm instance. Local instance fine.

Discovered an issue where on opening a door in a realm, it breaks and a door cannot be placed in approximately a 5*5 area where it used to be.
Placing a door there afterwards, the door will appear to be placed then instantly break.

Downloading the realm version and playing it locally has no issue.

Placing the door locally, saving and uploading to the realm, the bug happened again.
