just had a short discussion with @ToiletWraith in the discord channel and she suggested posting it here.
So I’ve been trying to rank up with my monster and got ranked Silver 1. I was around 1590 - 1595 progress points at the time. After a few matches I had this fight against three no-ranks and one Silver 1. I won the match and then saw my progress bar decreasing. When I peeked at the leaderboards my progress points decreased to 1588.
I’m not sure if this is intended (admittedly the match was pretty close), so if it is just close the topic. Otherwise: If I can provide more info about this potential bug, I’m happy to help.
