Due to an issue that could cause an instant game over when utilizing monsters with a half HP debuff as part of their Leader Skill, everyone received one Magic Stone for free!
This is the same issue as what happened on Japan server, which was noticed when JP players used Touya as leader. The error has been ongoing since forever, but not noticed till now!
