Larian Studios Forums Divinity: Original Sin 2 - The Modding Dungeon Divinity - Original Sin 2 - Modding Troubleshooting [bug] Copy map from 1 project to another.

Are you sure you moved all folders?

There's level data in:
1) Data/Editor/Mods/{YourMod}/Levels
2) Data/Mods/{YourMod}/Levels
3) Data/Public/{YourMod} (This contains assets and root templates. So for terrain there should be nothing in that folder you need to move. But it contains root templates you might have created and used in your level.)
