Same here, disappointed !!!
no headmaster after grinding out laso. My first halo laso at that. no skips. 
Add me tooā¦ Just finished my first LASO
(and i am 100% sure i have had ASO the entire time)
Andā¦ Noā¦ Achievementā¦
Fix it! 
yup just done it on PC and can confirm it still aint poppn 
would really love for this to get fixed sooner than later so i can 100% this game.
I filed ticket this is what they said, unfortunatly it did not work for me.
Thank you for submitting this ticket and confirming that all skulls were active during your game. Weād like you to verify if youāve done the following since you completed the campaign on LASO difficulty:
- Launch Halo Infinite Multiplayer.
- Ensure you are online and connected to services - try joining a multiplayer match to confirm that you are.
- Load up the campaign.
- Play the campaign normally, exploring and attacking enemies for at least 5 minutes
- Verify if the āHeadmasterā Achievement pops.
This was the response when i said it did not work.
Thank you for replying and letting us know that you did not receive the achievement.
Although we do not have an estimated time for a fix, the issue you experienced with the Headmaster achievement has been logged with our developers. They will use the information you provided during their investigation.
This ticket will remain open and I will notify you once our development team discovers a resolution or the issue is resolved in an update. I will also check in with you whenever a game update is released to monitor if the issue is still occurring.
Let us know if you have any additional information that can help us with this investigation.

Load of new achievements announced, but no mention of achievements that are currently in the game, and broken. Nice.

yea what the heck dude, twice in a row, once in july i finished it, and almost 3 months later i finished it again and they still havenāt fixed it, they need to work on this issue ASAP
Any update on that? Should I enter in a ticket as well because I have beaten it, fair and square, TWICE. If this had happened with Halo 2/Halo CE I would have LOST IT.
Check your achievement progress on Xbox. Mine has been stuck at 22% since the Season 2 update, it doesnāt want to progress at all.

Man this really bummed me out. I completed the LASO campaign last night and the achievement didnāt pop up. I made sure everything on the tac map said completed on legendary and before each session I verified all the skulls were on. I never thought to check the achievement on the Xbox menus. Of course it says 0% complete, but the load save percentage is at 99. Hopefully they get this fixed sometime, I have the LASO achievement for all the other halos I would hate not to have this one. Also I really donāt want to do it again since it took me 20+ hours to complete.

Any updates if itās working now? Iāve been grinding towards completion only to read this. My achievment is showing 0%, does this mean i will have to replay everything iāve completed when itās fixed?
Iām halting my playthrough until the winter update in hopes it will work thenā¦
UPDATE
Just completed this 5 minutes ago, made sure to load rather than continue.
Nothing, nada - 0% stuck achievement even though all 12 skulls are showing as active.
Iām not doing that again, they better give people that achievement.

From the Winter Update patch notes:
- The Headmaster Achievement will now unlock consistently.
- If the conditions for unlocking this Achievement were completed and it did not unlock in a previous version of Halo Infinite, the conditions will need to be completed again after installing the Winter Update.

Iām having the issue as well. I saw the patch notes, however, I donāt think most people are going to want to go through 20+ hrs of gameplay all over again just to have it pop. It needs to be retro awarded to those that had it done instead of forcing us to waste time in order to attain it.
Terrible
Thanks for testing @CriticalManc Iām right at the end and was about to try post Winter Update.
Iām glad I stopped as soon as it stopped tracking. I should now then be able to get the 4th tower in The Sequence, and my percentage should increase from 64%. Will try this now.
EDIT:
Nope. Nothing. Still at 64%, and thatās with both resuming the level, and restarting it. Seems that everyone will have to start again, or at least, restart levels on their existing saves, maybe.
