My FC has a medium house, and decided to split the top floor in half using a wall of partitions. It came out exactly as we wanted except for a small problem that I just can't seem to fix.



For whatever reason, whenever I leave the house instance, the partition moves ever so slightly, causing a minor gap. I can fix it easily enough, but it's still really annoying to have to do this every time I enter the house. Does anyone know whats causing this and how to fix it?
