So I just beat the ultimate weekly challenge which asks you to easily complete a mere five games of PVP Fiesta. I went on to win my first two games and the counter went up as advertised but when I lost my next two matches the progress bar never went up. I managed to win the next three afterwards and the progress bar went up and gave me the reward.
I’m wondering if 343 has labelled the challenge incorrectly and you have to WIN five Fiesta matches instead because surely losing and gaining no progress can’t be a coincidence right?
