Larian Studios Forums Divinity - Original Sin Divinity Original Sin - Mods Issue after changing level name

I've tried renaming the folder of the level, and ran into the issue of all the teleporters breaking (all the buildings are instanced). Didn't investigate further, because that was issue enough, but probably the same problem. What's the real way to rename a level? Haven't figured that out (but haven't looked THAT hard to be honest.)
