Upon completing the fifth mission in Halo CE’s campaign, “Assault on the Control Room,” the next mission titled “343 Guilty Spark” loaded and after the cutscene I saved and quit. Fast forward to the end of the day and I go to my campaign progress. It says I completed “343 Guilty Spark,” and when I load up campaign it takes me to some random checkpoint in the following mission, “The Library.”
The only thing I could think of was between those two events I did play co-op Heroic on the second to last CE mission. I don’t see how that would essentially give me credit for a campaign mission I never played though.
Has this happened to any of you guys? I tried to be as detailed as possible to assist 343 in fixing an issue if there is one.
