We're always working hard to make Roblox and run smoothly for all our players and developers, but occasionally, glitches do happen. If you find one, please alert our engineers to the issue by posting here. Remember to be as detailed as possible, i.e. What exactly does the glitch do? When did it start happening? Does it happen in one place or in all places?, etc. As it will make it easier for us to track down the issue.
