What error?

This is to select "finish massage" from Helen's first CG, and then continue CG. There will be two errors. If you repeatedly choose ignore when reporting an error, the game will continue, but the options in the lower right corner disappear and you can't watch their love and lewd.

If you repeatedly choose "rollback" when reporting an error, if you are lucky enough, your game will crash directly, but the next re-entry will not be affected. Otherwise, the menu and all buttons that should appear will disappear and no longer work. Quitting and reloading the game cannot be repaired, so it depends on luck. Like this.

However, if the next loading interface of the game is the main menu, it will be repaired. Until the bug is triggered again

Okay, this is a bug. Don't continue your game from this "Finish massage" options. Gallery is not designed to continue a game from those scenes. It's only for replaying a certain scene. Thank you for bringing it to my attention. I will fix it in the future versions.
