I completed all the skulls when I had no wifi not knowing that if you don’t have wifi you can’t get achievements. I have no problem getting the skulls again if I need to but they don’t respawn as the game registers me as having collected them already but Xbox does not. Is there anything I can do to get the achievements?
Aside from Iron skull, which can only be attained on Legendary, all the other ones are still there and can be found on Easy difficulty.
