I looked through a few different guides but can't find one that explains the problem I'm having. I can get to Korin's Tower but theres no option to talk to him. Apparently I have to use the item Korin's Spell to start the quest that lets you talk to him but when I use the item it says quest failed. Can anyone help?
EDIT: I was able to do the adult and master class quests. I had to forfeit ALL my quests and get rid of all quest related items. After that the option to forfeit the failed adult quest showed up. Worked like normal after I did that.
