I have been grinding out the monopolized achievement on MCC, and finally had a good time on some levels. Went to check how close I was to unlocking but found out that from the level Regret onwards no completion times saved. I was wondering if anyone else had this issue? and how did you fix it if possible?
i would suggest going to halo waypoint. when you log in you can see your time for each map. i had the same thing were it wasn’t showing my times in the game, but when i got a good time on gravemind it gave me the achievement. hope that helps
