I completed the achievement On Your Toes - H3: ODST: Find the 25th Audio Log. A month ago and it still has not popped. I have tried everything to get it to pop. I have signed in/out over a dozen times. I have popped several achievements since then. Waypoint shows it 100% complete but not unlocked. What else can I do?
Basically you’ll have to do to the 25th audio log again. I had a similar thing happen to me with the legendary campaign on ODST but luckily for me I just had to redo one mission that it thought I hadn’t completed. Wish there was an easier way, but unfortunately the xbox achievements system is a bit buggy for now. Hopefully it’ll be fixed in November.
