Larian Studios Forums Divinity: Original Sin 2 - The Modding Dungeon Divinity - Original Sin 2 - Modding Troubleshooting Rooftop not fading!?

I can't figure this one out. Both of these rooftops have the same properties, but the one on the right refuses to fade when a player enters it!

After some more testing, it looks like copying a wall and changing its root template to a roof is what breaks fading.

Can confirm this bug exist still, even worse is the official tutorial is what tells you to just copy the wall ontop itself.
Guess theres no shortcuts to prefection.
