After playing halo 3 co op the game said I had completed halo 4 when I was only 2 missions in and it said I had 10 out of 11 missions complete on ODST when I had finished the game
Same issue here! Except I was playing halo 4 now the game tells me I have completed 0 missions and that I have completed 6 missions on odst and I do not own that game!
