This is a problem. You should only see the name of your overarching persistent level here, TheCenter for example.
If you’re seeing the names of all of your sublevels, then you’ve done something wrong somewhere.
I’m not a mapper, so I can’t say for sure, but make sure your sublevels are all correctly assigned and referenced. In regards to the cook, I’m not 100% certain whether you need to include all the sublevel names, or if it’s just the Persistent level name and that provides a link to the sublevels for the cook to detect… you’d have to ask a mapper that. I would suggest asking on our Discord server, currently three out of five of our “Advanced Mappers” are online, so you may get faster help there.
