I know it has been a lot of time since this problem was solved, but I am experiencing something similar so I would like to ask for advice.
In my case, I am not using the “Open Level” node. I have a persistent level, which only has a camera and the UI. Then, I have a drop down menu where I display all the sublevels that I have stored in a specific folder, and when I click one, it loads it, and the other ones are unloaded.
The problem is, most of them are not unloading. All the levels seem to have the same settings, like the “Streaming Method” set to “Blueprint”, but only one level is unloading correctly, and I can’t figure out why.
I’m attaching the blueprint system I am using for this. Am I doing something wrong?
Thank you in advance for any help!
