So I fear I will never get 100% achievements. And I blame this on a glitch caused by 343's servers going offline for a few hours today.
You see, I had completed chapters 1 and 2 of spartan ops prior to the server shutdown, and when the servers went back online, it said I had completed chapter 2, but not chapter 1. So I re-did chapter 1, then continued on to do chapters 3-5.
After seemingly completing every chapter, I didn't achieve the challenge for actually completing every chapter. I went back and re-did chapter 2, but still the challenge remains un-completed.
Will the game forever have the idea that I didn't actually complete every chapter? Or is it just the challenge that itself is broken? Either way, I won't know until episode 5 is out and I don't get the achievement for completing every episode.
Has anyone else gotten this problem?
