I have finally seen 3 or 4 around. But is still strange, as in the first hours after the delivery you could already see dozens of random players with the nurse shown as main. That's the usual, people like to update with newest cards. The score during event was clearly favorable to that faction, but didn't seem something like five times more people on nurses side.

Having bugs in the reward delivery like you mention with the card level could explain the issue.

well sadly what happened is people looked at who was winning and then picked that team.
I imagine these events will always be a one-sided battle

i never got the reword and don't know y

Send a ticket. Because it was given out.

How many wins did you have by the way. You had to have 100+wins to get the card.
