The 21-year-old drove the second leg for Sweden in Oberhof and went in as fourth before the first, horizontal shot.
Then she pulled on a penalty round and collapsed in the results list.
Elvira Öberg left the embankment in 13th place 1.15 minutes from leading France and with the minute up to the podium.
- What happened?
Good question actually, says Öberg to NRK.
- It felt good lying down so I do not really know.
It messed up a bit with the first spare shot, it was simply not good.
She just wants to forget about the penalty round.
- Not fun.
It does not matter how good you go if you need to get into the round and tangle, it was a shame.
Jesper Nelin also drew a penalty on his round, in the second shooter.
Sweden finally finished in 13th place - almost three minutes from winning Russia.
Norway was second just behind and France third.
Linn Persson drove the first leg for Sweden and Peppe Femling - who replaced a bad-tempered Martin Ponsiluoma - finished the race.
- This relay is weak, now I look forward to the next, says SVT's expert Björn Ferry and refers to the single mixed relay which is run later today, then with Hanna Öberg and Sebastian Samuelsson in the Swedish team.
