I wasnt really sure where to put this bug at the first point but I finaly decided to post it here (Today page).

Even though most played heroes (in the expanded page) are being sorted acording to how many games you have played with that specific here, this sorting happens (probably) at DotA 2 launch, so some times its not sorted properly.

Its just a minor bug, but the solution is really simple as well (sorting after every single game), so theres no reason not to fix that =)
