Humanoids fall through Terrain and Parts

Reproduction Steps
So far I have only tested this on Treasure Quest and Islands and both games have the same issue.

Direct link to Treasure Quest: 🚨SOON🚨Treasure Quest - Roblox

System Information: Windows 10

Expected Behavior
When I join Treasure Quest, I expect to walk around just fine in the lobby. The majority of Treasure Quest’s lobby is Terrain.

Actual Behavior
As soon as I spawn in Treasure Quest’s lobby, I just fall right through the map. This only seems to be happening in new servers, when I join an old server everything is normal. When I joined a different game - Islands - I also fell right through the map. The map in Islands is made out of Parts, not Terrain, so I believe this happens for both Terrain and Parts.

experiencing this too. It’s really annoying considering I was about to release an update.

Experiencing the same on all new servers.
