So I did the Halo CE LASO playlist with my brother and he got achievements for completing LASO and completing a playlist. He also got the LASO nameplate. I didn’t get any of these things. It’s not like the other achievement issues where it says it’s done and unlocking. Those achievements say I haven’t completed these tasks even though I look at the playlist and it says 10 out of 10 complete. What’s to be done about that 343?
