Last Heart of The Swarm 10th anniversary achievement is bugged

The last 10th anniversary achievement in zerg campagin is broken because i have beat the mission under 18 minutes several times and i still didn’t get it. Does anyone have the same problem?

A bunch of achievements are bugged right now, XD

Are you playing the German version of the game? I remember reading somewhere here that the achievement is mistranslated (and not just this one) in German version.
What the achievement actually requires, is you need to destroy the 3 entrenched positions (the side guest / bonus objective, that is!) within 18 minutes to get the achievement. This achievement does work, the description just might be stupidly mistranslated in some other languages.
