Eye of the tiger bugged?

Been trying to get the ‘Eye of the tiger’ achievement for a few days now and finally got 20 consecutive headshot KILLS with no shots w/o kills. But I never got the achievement even after 3 or so more headshot kills right after.

Do the auto shotgun pellets that don’t hit something count as a miss for the achievement? Are this quest 3 achievement bugged?

I know some of the achievements are very buggy (like how I got the 100 kills with the MT 47 one when i hadn’t even touched a rifle yet) and was wondering if people were still having this issue in 2024/2025.

Been trying to 100% the achievements so this is really annoying.
