Thanks to a friend I noticed that since I started playing Reach PC I never unlocked any of the Steam achievements (even the basic ones like completing Winter Contingency). Why? Is there a way to unlock them now without redoing everything?
Update: It seems that cleaning the hosts file or reactivating the DiagTrack service (or doing both) fixed the issue, now every achievement done it’s unlocked, except a few ones but I think I just need to repeat them to unlock them
Can you explain in detail what you did I am having the same trouble and can’t figure out how to fix it.
