Hey - thanks for the bug report. Investigating the cause. If it helps I used an admin method to create the world in your project using your latest schema. Additionally, rooms should work just fine until we can find the root cause of the issue. Let us know if that can get you until likely Monday when we can deploy a fix.
Thanks Brit! No rush, just wanted to let you know and see if there was something I was configuring wrong. I’m just doing some prototyping - not urgent or a live service.
