Any% Glitched achievement still bugged

Hey !
Pretty much everything is in the title. Got that goddam mouthwash bottle in less than 35sec several times (even made 30sec), but the achievement won't unlock...

I know a patch has been released a few months ago that was supposed to fix this, but it's still not working. Any idea why and how I can get that achievement ? It's the last one to 100% the game >:c

Thx !
