I’ve completed the campaign 100 percent on legendary the month the game came out yesterday I felt like playing the campaign to kill some time. When I clicked campaign and scrolling threw the missions only mission one was playable I we started the game to see if that may help it did not. I lost all skulls and all campaign stats so I started a new campaign yesterday I was upset I lost everything since the campaign dlc will be coming out soon then just five minutes ago I go to play the campaign and it did it again back to mission one. I got to mission five yesterday now back at one … my multiplayer stats were not affected at all just campaign anyone else having this issue ?
