Larian Studios Forums Divinity: Original Sin 2 - The Modding Dungeon Divinity - Original Sin 2 - Modding Troubleshooting Story maps not showing up in engine?

Seems like that was what was missing. This guide or any other resource I found didn't really mention having to alter project dependencies (other than what the engine asks you to specify when you create a project), so I never even knew that was a thing.
It's working now. Thanks!
