Beat Campaign on legandary Glitch

Hello, I beat the campaign on legandary and the forunner level says I didnt complete it. I went back 2 more times and beat it again but it still says I didnt do it. Can anyone help ?

D: THAT’S HORRIBLE!! I’m Sorry To Hear That Try E-Mailing 343 Or Microsoft Or Deleting Your Data But… That Is Only For If You REALY Need To!! And Finaly Try Getting A New Disc But Before Spending Money Try Borrowing Someone Else’s That’s All I Can Thing Of Hope I’ve Helped :wink:

Some of the missions do not record when you finish them. Check to see which ones and replay them. It worked for me but was aggravating.

Make sure your connected to xbox live

It does work
