I went and used transdimensional paintings in my condo (Art Studio in this case), and when I came back the next day they weren’t showing the right location. When going through it, it worked fine however, it was only a display issue.
Editing the painting forced it back to the correct displayed location.
Steps to Reproduce
Place a transdimensional painting (mine was 8x8x1), put a location in it (away from the main area), disconnect and reconnect and look at the painting again.
What I expected to happen
The painting would display the normal set location.
What happened
The painting displayed the incorrect location until the edit window was opened. (It actually went to the right place, only displayed the wrong location)
