10/26 Update: We deployed a small server-side hotfix today to address an
issue preventing Mercenaries MMR from properly adjusting after players lose a
game at 0 MMR (such as players who lost their first-ever Fighting Pit game).
The patch also prevents a hack that allowed players to cheat more than 6
Mercenaries into their Party. This is our last planned hotfix for the 21.4
patch cycle. Look out for future updates in the 21.6 Patch Notes, coming
later this week, ahead of next week’s patch!
