Happening now - During the opening season of the New Bloom in DotA there has been a crazed all over the community about the 9999 mmr in Solo and Party ranks. No one knows that cause of it yet and no action at the moment has been taken into action by Valve.
There are many claims that after the update, players were in the low priority pool. Because of this bug some players can't queue and play rank. In that case, they can't gain the New bloom points because of the inability to play on rank. Although players can get points on regular matchmaking, some people just want to do it on rank.
