LeBlanc Shadow of the Rose Blood Moon

LeBlanc's ulti re-cast in Blood Moon can walk towards nearest invisible champion.

When you cast her R twice in a row, resulting in Shadow of the Rose being placed where you cast her R in the Blood Moon game mode, I've had it go running towards invisible enemy champions with the buff specific to Blood Moon, instead of the nearest visible enemy champion. It's only happened to me once or twice, but it seems pretty easily re-createable.
