 After missing the 2011 World Championship due to the injury, Fak entered the 2012 World Championship as a member of Slovenian team.He won two medals, a silver in the mixed relay (together with Andreja Mali, Teja Gregorin and Klemen Bauer).Although Slovenia crossed the finish line as first, 8.2 seconds in front of Norway, the jury awarded bonus seconds for the Scandinavians because one target did not go down despite their last runner Ole Einar Bjørndalen hit it and therefore had to take an additional penalty loop, which put them ahead of Slovenia into the first place.
