Same bug has occurred twice now.
Bug 1:
It seems placing any potion on front shelf prevents you from continuing a game.
Bug 2:
Gallery does not unlock in main menu, so you can only view it in your current playthrough. This means that starting a new game to get other scenes, deletes anything you've already unlocked.
Bug 3:
Man-at-arms quest for Steffa seems to break at second interaction.
