Ok, so yesterday I got the last two achievements in Bayonetta, but they didn't count in my overall gamerscore nor do they show in the Bayonetta achievement list. I'm stuck at 880/1000.
One thing that did happen while I was playing was I got a message saying "disconnected from Xbox Live". I checked the dashboard and it said I was still online. I figured it was nothing and kept playing. I wonder if that has anything to do with this. Anyone experience this too? Really frustrating to spend all those hours on a completion only to be fucked out of it.
I haven't had it happen in a while and I honestly forget how it happened when it did. Regardless, I remember my gamerscore on Xbox Live and TrueAchievements at one point didn't add up. As long as your achievements show as unlocked, it should eventually fix itself. Nothing you can really do iirc.
