This has happened three times to me in the past two days. After finishing a ranked battle the player of the match comes up as in the image below. Looking at the stats you can see something is messed up as it says there was 13, 665 flags delivered and returned. After clicking continue the results page is all in another language (I am assuming Russian) and I do not receive reputation points or blueprint points. However, I do seem to receive experience points that apply to my rank. I am sorry I do not have a screen shot of the results page. I will add one once it happens to me again.
