Thanks for the report! We actually ran into this issue during testing as well—it wasn’t expected. It’s likely caused by the save system behaving like a rollback, which also affects the gallery room.
I decided to try a theory, if you have all the gallery unlocked and log out in the gallery room, the scenes you have watched should show up. Everything does work now for me, the shards don't show up but I can still access it. I didn't know if you knew of this way to get the gallery to show stuff.
