Hi Jienagamblu! In the current version, you can only buy the Glasses Level 2 during the tournament event, but I’ll make them available to buy in the market after the event too! 😊
About the Yoru bug—I just tested it and it seems to work normally. My guess is that if you dream again, you’ll find that 1 of Yoru’s gallery pictures isn’t unlocked because your save already skipped that event. I think if you go NG+ again, you should be able to unlock it normally!
Sorry for the late reply—work’s been super busy lately and I’ve had to do a lot of overtime. Thanks for your patience and for playing the game! Let me know if you run into anything else!
