Select players in the 2v2 bracket were mistakenly awarded end-of-season awards and titles. This was due to a game bug, and not at all intentional. We will be removing the mistaken awards and titles. For some players this will occur upon logging out. For others we will correct the error on the next maintenance period.
We are very sorry for any inconvenience or confusion this may have caused.
