You shouldn't have to, is the entire gallery locked?
Because if it's just a few scenes, then it might be because I had previously messed up one or two of the gallery entries and fixed them for this update.
Huh, odd. You also moved the persistent save file? Because that's the one that should keep track of the gallery.
Also just to make sure, they've been moved into the save folder that exist in /C:\Users\???\AppData\Roaming\RenPy\TroubleiNTheaRena- ?
If they're just moved into the save folder within the game folder, it might not register correctly.
