Hello
I would be going through halo anniversary campaign and constantly after i finish a level on legendary co-op. I would save and exit after it has loaded the next level. Than when i reach the home screen where is says how many levels you have completed, it than says i have not completed the level on any difficuilty even though i had finished the level and gotten the achievement for it. Though it says i have not even done it before and it did not only happen once. Since the release it has happened 4-5 times on me. I thought the update earlier might have fixed the problem however i just did the level 'two betrayals' on legendary and afterwards it said i had not done it. This is getting quite frustrating. Please do you best to fix this problem. Also the scores / times after the level are sometimes not saving.
