Hi, I do not have the chinese version, but I still have a bug too with the gallery. When I launch a scene of the gallery, when it's finished and I want to go back, clicking to quit the gallery or to load a game just launch a random gallery scene everytime, is it normal ?
No it's not normal, the gallery implementation is quite wonky indeed. Think of the gallery scenes as a playlist that plays them in a specific order. If one ends, the next starts playing. The gallery screen you see at the end of a scene is kind of "fake", you're still in gallery mode, which becomes apparent as soon as you close the gallery. Pressing ESC enough times should get you out of this. If you're on Android then though luck; it's probably best to restart the game if that happens.
