yes ive tried doing that but the portal just wont show any options there's just a portal there and no additional options to go to the world
do i need to maybe get the rest of the girls to max level
Hmm, I don't quite understand what you mean. You don't see any options to click or you see at least a 'back' or 'cancel' button? If it's the later, you may be missing a quest or level, yes. If it's not that, it may be a bug.
might start up a new save and try that il keep you posted thanks anyway
