I was trying to get terrain from one place and copy it over to a place with team create mode. I called the Terrain::CopyRegion method and parented it into Lighting with this line of code:
workspace.Terrain:CopyRegion(workspace.Terrain.MaxExtents).Parent = game.Lighting
The new object was created successfully, but merely copying and pasting the TerrainRegion into the game with team create enabled causes the entire place to crash. To mitigate this situation, we had to disable team create, insert the object, copy the terrain over using Terrain::PasteRegion, and then enable team create. Little that we know that enabling team create with the TerrainRegion object in the game would cause the entire team create to crash and lock us out of editing the game.
Note to admins: This is the place in question. https://www.roblox.com/games/597979886/Project-Aurora
Two requests to the admins:
1. Please clear the game and disable team create so that we can upload the latest version once again. We have favorites, visits, and whatnot on this game so I'd rather not throw this game instance away entirely.
2. Feel free to dissect the linked game (prior to clearing the game to an empty map) to decipher the bug!
Pinging @Polymorphic so that he can state his consent to the admins to follow up on the two requests (as he owns the place we are collaborating on).
