The scoreboard came in the second period at 1-1.
Martin Stohanzl was only going to throw away a finish before a change - but it instead resulted in goal celebrations.
Färjestad goalkeeper Matt Tomkins would only push away the finish that came from halfway.
Instead, the puck, via Tomkins himself, was directed into the goal.
A mistake that meant away lead.
- It's never fun to watch, says expert Jonas Andersson about the strange goal.
Guests from the Czech Republic then went up to a 3-1 lead, but Färjestad managed to respond before the last period - after goals from both Marcus Nilsson and Remi Elie.
Never met
The two teams, who had never played against each other before, then settled in the third period.
Then Joel Nyström struck with a fine goal in the power play.
Nyström slid out to the right before putting the puck right up in the left crossbar.
1-3 had become 4-3 and home lead.
A result that also stood up to the match now.
The victory means that Färjestad now has a slight advantage before the return match.
The round of 16 is played over two matches.
The second leg will be played on November 22 in the Czech Republic.
