I agree with this person, as you play so many battles to micro upgrade to the next M level and it doesn't acknowledge it. You don't get it for free? You painstakingly earned it. Not allowing a person to upgrade to the next level is a bug that needs to be resolved. Are you trying to force players to give you money for the next M level instead of them earning it through their skills through the micro upgrading process?
