Soul of Iron (Seaon of Mastery) bug

So i just logged into my lvl 60 DK and got the Archievment Soul of Iron (Seaon of Mastery) eventho i have no char on 60 in Season of Mastery nor did i try that no Death thing on it, for some weird reason i got that Feast of Strengh now on him idk why lol

Same thing here. My fried got it and he never even made a character on SoM realms.
