Hi again, I haven't gotten through the entire update yet. But it looks like new entries in the gallery aren't being unlocked.
Are you playing on mobile? There is a bug with the mobile version at the moment were gallery unlocks appear and disappear, I will see if I can find a fix for that for the next version, there will probably a way to just unlock all gallery entries with a cheat in the end so you don't end up losing them again.
