Jink Ult (Gamplay)

This bug may have been a one time thing or might have been fixed in the 5.1 patch but I figured I would inform you just to be safe. For some reason while I was playing a game Jinx's ult passed right through me as I was playing as Malzahar. I wasn't clipped or some stretch of hitbox it was dead center on the champion and it ignored me like I was minion. I think it might of had something to do with a voidling being in close proximity, maybe it registered to pass through the voidling and then continued to pass through me before it reset or something. I've only seen it once and I haven't tried to recreate it but I know it happened because I asked everybody on both teams and they saw it happen too.
