I have this exact problem and have a support ticket open about this.
We have one of the old clan halls and changing the spawn room to a newer clan hall shifted all the transporters out of bounds, except one transporter i placed in an open space room. Along with the transporters _some_ decorations shifted with it, but not all. Its weird af.
The problem is: i cannot remove the out of bounds transporters. So we're waiting for manual removal by support.
Edit: Also the problem with spawning in locations other than the designated spawn room is happening with us too.
