Big thread developing over achievement problems at Halo Waypoint - https://www.halowaypoint.com/en-us/forums/84ad72a8b51847978545f685f651fc15/topics/achievements-not-working/3f30843e-6f5b-45ca-8d7f-7b6e49f92a9e/posts I did a quick search but didn't see a lot of posts here about achievement problems here. What I've encountered so far - Completed Achievements not unlocking or showing as 100% - 1. Pillar of Autumn - Halo CE: Complete The Pillar of Autumn. 2. Halo - Halo CE: Complete Halo. 3. Skulltaker Halo: CE: Mythic - Halo CE: Find and claim the Mythic skull in remastered mode. 4. Skulltaker Halo: CE: Boom - Halo CE: Find and claim the Boom skull in remastered mode. 5. Sacrifice - Halo CE: Activate Terminal 2 on Halo. Achievements successfully unlocked - 1. Just Getting Started - Kill 100 enemies or players. 2. Balaho's Most Wanted - Kill 100 Grunts. Achievements unlocked successfully - THEN RE-LOCKED 1. My Buddy Chips - Halo CE: Fight alongside Chips Dubbo and listen to his words of wisdom. ^ How can it re-lock? Yes, I'm saying this achievement successfully unlocked but is now showing as locked. I've also lost all progress functionality in the achievements app. Earlier I did see a few listed as 100% with the word "unlocking" awkwardly beside it... Now those are gone, and all achievements like the "Kill 100 Elites" show as 0%. Additional information - - I've tried a hard reboot of the console. - I've signed out without Halo running, signed in and re-launched the game. - I've signed out with Halo running, signed in when prompted and continued. - I began playing around 1pm PST - I'm using the disc version - Any sort of stats screen via 'Career' times out and tells me to try again later. Thanks, hopefully this can get sorted out soon.
