I can move my Training Room, Staff Room, Analysis Room, all fine. Almost as soon as I move the Workshop the game closes. I have tried different orders of moving rooms with no change. The only other oddity is that the first time it happened, my Marketing Room vanished from the map when I reloaded. It still crashes before I added it back, and I tried adding a new Marketing room and it still crashes when I move the Workshop.

If I create a new Workshop, I can move that just fine.

I haven't tried deleting the old one in case you want my save files for investigation.
