Something similar to this happened to me yesterday.
Studio kept failing to save / publish, and I just closed it and lost so much progress. A workaround I had to do was save the whole game as a file, then transfer almost all the assets and replace them in the original game.
Hi, We are unable to reproduce this bug. Please file a new bug if the issue happens again with placeid, studio logs and steps that lead to this.
Sorry about late follow up. It could have been due to an issue with Roblox services at that time. The original issue has likely been fixed.
