In the side-quest "Say no to fueds" you have to go into a dungeon called Nepeta Mine. The first time I entered it acted normal but I didn't complete it. now when I try to re-enter, it won't allow me to continue. and it is only happening to me because a friend of mine was trying to help me with them entering first, joining the first battle, then I port to them. But when I ported into the dungeon and in the fight, the fight just ended and my friend just started. I just want to know if this is something that can be fixed.
