Dundee Stars' assistant coach Nikita Kashirsky has warned his team to eradicate mistakes to retain hope of winning the Gardiner Conference.
A 4-2 win at home over Edinburgh Capitals on Saturday was cancelled out as the Caps turned them over 4-3 at Murrayfield 24 hours later.
"Finishing the weekend top of the Conference certainly makes it a positive for us, but we can't rely on other teams doing our job for us," he said.
"It feels like we've been shooting ourselves in the foot and all the goals we lost this weekend all came from mistakes by us.
"We know Edinburgh can beat good teams, but we have to be more careful and more disciplined when we take penalties."
Dundee's weekend started well when new arrival James MacLellan found the net just a minute into his debut against Edinburgh, who levelled through Peter Holecko.
Brock McPherson restored Stars' lead with MacLennan adding his second soon afterwards.
However, Curtis Leinweber pulled one back for the Caps in the final minutes, but John Dolan killed Edinburgh off with an empty net goal at the end.
In Sunday's rematch, the Caps got the best possible start when Richard Hartmann found the net, before Dolan equalised.
Jeff Hutchins scrambled in from close range before Dolan made it 3-1, as Dundee opened a gap.
Edinburgh fought back with Marcis Zembergs reducing the arrears then Leinweber levelling before he scored the winner with six minutes to go.
And Caps' top scorer Leinweber was pleased his team ended their 11-game losing streak, hoping it could spark a positive end to an otherwise poor season.
He said: "It feels good to get that monkey off our back of not winning those 11 matches. We have games where we should have won, but we're pleased at this one.
"Mathematically, we're still in for the play-offs. You're never out until you're out, but there's maybe more pride in our performances.
"Dundee are a good team and have done well, so it's nice to get the win. Hopefully, it's the start of something."
With the Stars losing and Sheffield going down in Cardiff, it clinched the Elite League title for Belfast Giants, who have won it twice in three years.
At the other end off the table, Fife Flyers are continuing their play-off bid, sitting seven points behind Cardiff Devils.
After being 4-0 down at home to Braehead Clan on Saturday, they stunned Glasgow by storming back to win 6-4 in Kirkcaldy.
Two for Ed McGrane and single goals from Joel Champagne and Mario Larocque gave Braehead what they thought was a comfortable lead.
But Justin DaCosta kicked the comeback off followed by finishes from Derek Roehl, Steven Gunn, Kyle Haines and Tim Hartung. Haines then added the sixth.
They kept that form going into Sunday by dispatching Hull Stingrays with a 7-2 win, making it five wins from six for the Kirkcaldy side.
Jordan Fulton opened the scoring for Fife five minutes in before DaCosta added the Flyers' second followed by Hartung with the third.
Guillaume Doucet salvaged one for Hull, but Ned Lukacevic scored twice near the end of the second period to make it 5-1 before Omar Pacha replied for the visitors.
Fulton then made it 6-2 for Flyers with his second of the night with Gunn rounding off the scoring late on.
As for Braehead, it ended up as a weekend to forget as they followed up Saturday's collapse in Fife with another poor loss on Sunday at Coventry Blaze.
Michael Devin and Ryan Ginand put Coventry two up before Mike Egener and Adam Henrich made it four without reply for the home team.
Joe Cullen found the net with six minutes to go with Larocque adding Clan's second shortly after, but it was to be in vain as Clan ended the weekend pointless.
