Yuumi Global Invisible and Untargetable Clone

In an ARAM, the enemy Yuumi would disappear from the map (screen and mini) and reappear in a completely different spot (too far to have walked). This glitch clone stood in 1 spot and was untargetable. It would mimic the animations of the real Yuumi when the real Yuumi started using abilities, after which the glitch clone disappeared and the real Yuumi reappeared on the map.

The bug seemed to happen when Yuumi detached from a champion and had no other champion to attach to. This meant we would wipe out 4 of the enemy team, but almost never killed Yuumi because Yuumi was nearly always invisible when alone
