France won by 53 seconds over Norway. Germany came third, a further 35 seconds behind.
It was when Anna Magnusson lay down for the prone shooting that the rifle strap came loose. She told SVT that it was probably her who hadn't checked in a long time whether the screw was tightened.
"It usually sits tight, so I don't usually keep working on it. It's frustrating. You don't become your smartest self, you're stressed and tired," she says, explaining that it took time before she realized she could screw the thread back in.
Magnusson lost more than a minute on the mistake and then lost more time on the track and at the shooting range when she needed three extra shots in the standing series.
Anna-Karin Heijdenberg, who was competing in her second World Cup relay, lost further time due to a penalty loop in the prone and three extra shots in standing. And Hanna Öberg was also forced into a penalty loop after missing the targets in the prone.
Elvira Öberg, who won the sprint race on Thursday, only missed two shots and moved Sweden up from tenth to fifth place.
