[Gameplay] YUUMI BUG EXCUSE ME???

I'm a M7 Yuumi who loved her since the day she came out and have been on both sides of a Karthus ult, but all of a sudden Yuumi is immune to his ult WHAT

The particles are over her head but she takes zero damage EVEN WHILE DETACHED, EVEN THOUGH THAT DOESNT MATTER IVE BEEN HIT BY IT WHILE ATTACHED BEFORE

her partner died while i was channeling and she was forced out but took no damage from ult, i was channeling while she was out and she flew to a teammate as the ult hit AND SHE TOOK NO DAMAGE

my Soul Harvest wouldn't even proc because the game said i did not hit her
