So just to clarify, they're locked for the 3.30.0 version? If so it would explain the probable codename change for scenes in the coding as you mentioned before, which I can't really do anything about right now since I have version 3.29.0 in which all scenes are unlocked with no issues, I would have to wait until version 3.30.0 is released for the public (non-patreons) to get the new and fixed profile.json file.

So apparently on my end the apk it downloads is still the 3.29.0 which is actually the one I download first and use to check if new scenes are added (I don't really look at the changelog tbh), hence why I didn't notice that it was indeed supposed to be 3.30.0. Luckily it did download 3.30.0 for pc, however after attempting to unlock the new scenes, while most of them actually unlocked, for Puca either 1 scene changed and it didn't unlock or it relocked it for some reason (possibly due to a codename change, unless it's a bug in the new version), while the 3 new scenes didn't unlock at all either leaving 2/6 unlocked if we exclude 'Normal'. I don't know why it isn't unlocking the scenes for Puca specifically but I'll test and see what I can do, which is not much if I'm being completely honest so no garantees. I'll also update the profile.json in my previous comment for the time being.
