Valve's repeated attempts to fix bugs with Hand of Midas have led to an issue with the interaction between the item and Ogre Magi's ultimate ability, Multicast.
Regardless of the level of Multicast, the item does not trigger multiple uses if it has fewer than two charges. When using a single charge of Hand of Midas, the visual effects of Multicast still appear over the hero, but only one creep dies, and gold is awarded only for that single kill.
Previously, a Reddit user with the nickname UltimatePlayerr showcased a new bug with Hand of Midas that allows the item's cooldown to be significantly accelerated.
