Version 65 Release Notes & Status - Discussion

It better, indeed, be A coin and not another “you’ll need 100 useless farming of valueless coins to do what an EHT does for free and with only 1 of them (w/ probable costumes if the Event Hero has one).”

Not sure what the wording means, but I imagine it’s referring to Map Stages where the boss waves or elite stages feature multiple bosses/enemies that have Special Skills. Though, since it’s under fixes, I guess there was a weird bug where she’d only target that enemy (without having the player target) instead of being like a normal Hero.
