I’m using 4.7 Preview 3 right now. I have a custom structure using three variables: an enumerator entry, a class of a blueprint which has another blueprint I made as parent class and a userwidget. Everything seems to work until I go to my blueprint called “Database” (a simple actor for storing data, read-only) which has an array variable using this structure. I need to fill default value of it with data. I tried using other methods but they resulted in problems and that’s another issue and default values should not cause troubles so I stay with that approach. When I close project and reopen it, I get this:

Previously variable was just disappearing when reopening project until I compiled database blueprint. But now I either have to delete and redo half of my widgets and blueprints or use a backup version. I hope this can be fixed somehow. Let me know how I can help. I can send you project, I just don’t want to make it available for everyone. Thank you in advance!
