Hi @Damp, somehow when u published your game it should be display automatically on your Profil or Group Experiences. When not then you’ll need to go to your game by clicking it on the website, than you find three dots up, right corner and click this button, afterwards you see a button called “Add to Profil”, click it then you go. By group you need to go to settings then group settings and click the “Show Experiences” or so. But to have 1 experiences and connected on profil and Group, isn’t possible actually, maybe he just copy it?
I think you have to make the game on your profile first and then add it to your profile, then you need to transfer ownership to a group. Since the game was never deleted or anything, the game still sits on your profile. This is slightly speculation, but I’m assuming this is how it’s done.
