300-400 Acheivement drop

Hi. Weird question... Wasn't sure where to ask this but I noticed over the weekend, I was achievement hunting. I didn't screenshot anything unfortunately but oddly thought I should and now regret it.

Anyway. On Saturday 5th late or early Sunday 6th of April 2025, I went to bed with 10.1k or 11.1k achievements on my profile. I then logged in next day (I work second shift) to only 9.6k achievements and I wasn't sure what happened (I have since gotten ~300 additional achievements, back up to 9,999 exactly).

I already asked a few AI and couldn't get any decisive info other than to check my recently played games and/or look for games that recently de-listed achievements. So tldr I lost 300-400 achievements this weekend and wonder what happened (the game I was playing was "Zup! X" if that helps).

Anyway I'm clueless how ~300-400 achievements just vanished from my profile or why they ghosted appeared as 10.1k-11.1k (can't remember which) on late Saturday night/early Sunday morning.

Thanks! I am aware many games are "pulled from steam store" such as Rocket League for example but I think your achievements for those stay on your profile so I know it's not that.

The achievements stay. They are no longer counted for the profile, though.

Could also be a temporary glitch. Sometimes earning a new achievement can force Steam to recalculate them. If that doesn't fix it, it's most likely a game was delisted.

Thanks that's about what I thought. I tried earning some new ones on Zup for that reason and the ghost achy's didn't come back.

It's no big deal was just hoping for some visibility maybe someone knew how to find recently desisted games (one AI I asked said to try "steamdb.info" for this but I couldn't figure it out).

Thanks! That's what I was assuming, glitch or de-listed. But I can't think of any game I had 1,400 or 400 achievements in that is de-listed now.
