I have beaten halo 4 campaign and spartan-ops on legendary skulls on solo and co-op but the game has relocked all my missions and says i havn't completed anything also it resets all my spartans points to 52 and relocks all armor abilities, weapons, tactical/support upgrades and resets all my load outs everytime i turn halo 4 on. I have been a SR130 for a long time now and have completed the entire game i've been playing halo since launch. can someone please help me?? Gamertag= Bushi Sensei
