This is still an issue in 1.1.2.1. And for me I have to stash and replace the mover itself to properly disconnect not the object that was previously connected
They do connect, but you wont actually see it until you rejoin, I had this happening when I was adjusting the elevator mover in my last condo, if I unlinked the mover, then grouped more shit to the elevator, then reconnect the mover, the new shit wouldn’t move with the elevator, but if I left and reloaded, the new shit was actually attached to it and moving properly.
The game has MAJOR issues with condos right now in several areas, especially for clients. At some point they’re gonna need to stop adding more and more stuff and go back and fix all the stuff adding it broke along the way.
