Why is there an option to allow players outside a league to enter another league hall? It still doesn't work. I can still give outsiders permission to enter my league hall. They don't get the option to enter.
Haven't been able to test this, but I wonder if that function only works via the lair teleporter+tele mod for bases & league halls. If so, that is not cool. No bueno.
It works, i go into my friends all the time plus my heroes can enter my villains hall and vice versa. Go to your map in the start menu, hit Base Tracking, pick the hall, then update. Then you go to HoD or Watchtower and enter their halls through the teleporter. Hope that helps!
