Halo one achievement saying i done them not unlock mission 1,2,3 complete why is this so
There is currently an issue with the Achievements populating for some people. You are probably having the same problem the others are. 343 is working on this as we speak. You should receive the achievements later.
343 is working hard to resolve issues like this one. Many people including me are expericing that issue. Give it time. Also after after a while the achievments will randomly pop if there locked but completed…
Same boat - hopefully they will unlock soon enough…
