In my achievements page, some categories got reset back to zero during the last stats system upgrade.
This resulted, for example, Lone Wolf showing just one win, and Coalition Activist showing 4 wins currently. Meanwhile if I go to my statistics, I can see that I have 58 wins total, which is correct number.
So it seems because of this bug for some achievements that I had close to completion, I will have to start them from scratch again.
Please take a look at the attached screenshots.
