I’ve been working on UI in my game for the past few hours and tried to restart studio. When I did I get this error every time I try to re-open the save file. I also have no autosaves for the file, which is weird because I have it enabled every 10 minutes. I can also open other place files just fine, just not this specific one.
This happens 100% of the time on my Windows 10 Google Chrome version 86.0.4240.198
The feature was reverted around 5:04 PM, so you should be able to open the place now. This should not have caused place corruption, so all of your changes should still be there.
