MouseBehavior no longer working in studio

I noticed a few weeks ago that some of my games would have their camera stuck in studio but not in the client. The simple issue is that MouseBehavior no longer sets in studio. I’ve tried it in a new baseplate, I don’t know if this is a known bug or not.

repro:
game:GetService(“UserInputService”).MouseBehavior = Enum.MouseBehavior.LockCenter

Tested with a few friends and it’s ONLY happening to me. I restarted studio and everything. This is a huge bummer because I can’t work on a new game I had planned. :frowning:
