Ok so I'm playing alongside my son we have both done the same quests but now that we have hit mooshu none of the quest givers have the side quests available to him ... is this a glitch .. how can we fix this??
If he truely is in the same place as you (in quests), and is the same level, it may be a glitch, if this problem is not resolved within a few days, I would recommend sending a ticket to the support team. Good luck, have fun in the spiral.
