Larian Studios Forums Divinity: Original Sin 2 - The Modding Dungeon Divinity - Original Sin 2 - Modding General Cannot play level?

I cannot put my custom level into a GM scene? I had previously heard to just copy the level into an add-on but for some reason it deletes almost all my custom NPC characters when I copy it. Any tips? I was hoping to play today after spending 30 hours creating everything.
