So recentantly I was doing some pet derby. I was helping a friend in the Portico, when my next (ranked) match started. I was on a Teen Dragon, and I was doing pretty well, in first by a margin. However, when I crossed the start/finish line to start the second lap, it still said I was in lap 1.
And in third place (out of 3).
So the rest of the race I was still trying to win. Both opponents finished as normal(a Burning Pixie and a Brown Spider, both Teen). After I was done with what should have been my second lap, it said I was on my second lap. After three laps, I finished in third. By two minutes. My pet ranking went down by 10 points because of this.
I'm very upset, and while you cannot redo this match, I would love to never see this happen again.
