I have unlocked dozens of achievements following launch day of the MCC. In addition to the crazy amount of bugs in this game I have had huge amounts of trouble with achievements properly unlocking. Currently I have 4 achievements stuck in “Done! Unlocking…” Xbox phone support is pointing fingers at 343… No surprise there! What is taking so long!?, this has to be the most bugged game ever released! I really cant believe these issues haven’t been fixed after days of time! makes you miss Bungie more and more!
I’m in the same boat as you but with what bungie faced in destiny and quoting 343 we deserve better shows they care. How many times has a comany shipped out four games in one with success. I have 6 achievements not unlocking such as “Cario station”, “Outskirts”, “The Arbiter”, “Gravemind” and Uprising… not only that but I did the halo 2 legendary campaign with only the grunt birthday party skull and iwhbyd and never got my legendary achievement either, the 6 mission based ones show a locked sign as they do to yours followed by done! Unlocking… the best you can do is be patient.
Problems with terminals and skulls there (and 3 missions), i think it’s MS and not 343, i got the same problem in many games where i need to do 2 times the achievement to unlock it…
4 remastered games all not working for me to 100% Single Player or Matchmaking.
I know the feeling. I have 6 glitched, or bugged or whatever we should called. Mine are also Cairo Station, Outskirts, Metropolis, The Arbiter and Oracle. I have replayed the missions over many times but still nothing. Hopeful they might just reset the bugged ones or just unlock it…it does say Done! unlocking…after all.
So I tried playing the first two missions of Halo: CE and still they will not unlock the achievements for Pillar of Autumn and Halo. They still say done unlocking but wont unlock. Please tell me the update that is coming this weekend will fix this problem Other than that I’ve been able to unlock the other achievements in everything else that I’ve done.
