Today I recovered my gamertag on my brother’s xbox to help him beat the campagin on legendary. I currently have all 44/44 achievements. But we noticed after I recovered my gamertag on his xbox, everything I unlocked became unlocked for him, and therefore there are several achievements he cannot recieve. For example, no skulls appear for him even when he’s playing by himself now, yet he has all skulls unlocked even though he only unlocked 1 skull (which was before i recovered my gt). Anyone else experience a glitch similar to this?
