The Scottish side, Aberdeen, who are already out of the competition, continued their Europa Conference League travels with a trip to Finnish outfit HJK Helsinki.
Hassane Bande opened the scoring for the hosts before Santerri Hostikka made it 2-0 in the 33rd minute.
Aberdeen hit back thanks to a stunning half-volley from Angus MacDonald, but play was paused moments later due to their fans, who were seen throwing snowballs at opposition goalkeeper Niki Maenpaa.
Referee Genc Nuza then appeared to encourage Jonny Hayes to run over to the Aberdeen fans and tell them to stop.
With the snow still falling, reporter Archie Rhind-Tutt said a tannoy announcement hinted the game could be abandoned if it continued.
Even Aberdeen forward Duk appeared frustrated with the fans and play eventually got back underway at the Bolt Arena.
The Cape Verde international proved key for the visitors soon after as he headed in to make it 2-2.
Aberdeen are still winless in the Europa Conference League group stages though as they sit third in Group G.
A 2-1 defeat against Eintracht Frankfurt was followed by a 1-1 draw at home to Helsinki, with PAOK Salonika then beating them 3-2.
The group leaders were held by Aberdeen in the reverse fixture and the latter then secured their third draw on Thursday night.
Despite their efforts, they will not progress to the knockout stages next year as they can only finish third or fourth in the group.
Aberdeen’s focus will now switch back to Scottish Premiership action as they sit tenth out of 12 after a poor start to the season.
