Larian Studios Forums Divinity: Original Sin 2 - The Modding Dungeon Divinity - Original Sin 2 - Modding Troubleshooting Publishing GM mod issues (story mode?)

Hey folks,

I'm trying to publish a GM mod locally to test out, and I notice contrary to the larian demo "first mod" video on youtube, when i have set my project settings to target GM mode, the publish window still states "Story Campaign" / "GM" and no "addon".

Is there something rudimentary that I'm missing?
It is likely that i loaded assets from story, arena and GM, because i wanted to access all assets, is this likely the issue?
