TrueAchievement Score stopped updating

I reached 155,000 on the 22nd after finishing Vice City, the following day I finished the Bozak Horde on Dying Light and another Misc achievement on the following DLC the day after but my TrueAchievement Score stayed at 155,000.

I started the DLC for Grid Legends today and the latest achievements have accounted for my TrueAchievement Score, so is there a reason the Dying Light ones haven't been added?

I reached the Milestone on the 22nd, and the 23rd/24th achievements didn't count?

Thanks

Just to add to this, I got another achievement in Dying Light that was worth 15 TrueSteamAchievement Score but only 9 points got added to my total?

TA score can also decay. When you get scanned, new points are added for the new achievements, but for other achievements, the TA score might have dropped, and therefore it will look like less points are added.

Oh that makes sense, so it could be that an older achievement has lost its value due to not being as rare?

That's correct. It also happens with new games and DLC as well where the influx of new players increases the TA score (more players and less with achievements). Once that settles and more players are getting achievements, the score drops and evens out over time.

e.g. an achievement on Xbox from Forza Horizon where there were a lot of players, and only a handful achieved this one. It was worth 5000 TA score. Then, when people started unlocking it more and more, the score dropped to 250-ish:
