you may wanna talk to mayu, my problem solver was talking to mayu about halloween and one more time for fixing the gate, then pick up the broken gate and pay mayu 80wood, and bring the gates when yui is around
I have the same problem just that i dont see chika or hana around and if i speak to mayu she just says she's Busy and i already bought the Gates to mayu(dont know if the reason maybe is that I still have version 3.0?)
