Was playing an ARAM when quite abruptly the ball disappeared when it was hovering over Orriana. I could still cast it and it would show up on the ground, but disappeared when Orriana picked it up. It showed up for E (when casted on other people) though. Not sure if other people could see it. Sorta annoying.
Thanks for looking 
Riotmoonstones2 votesHiya!
This is something we are aware of. It's affecting all skins, as well as the base. We're still looking for a solid repro for this one. Thanks for the report!
A unused condom1 votesI'm not sure how to reproduce it, You could try playing with a Lee Sin, Varus, Kassadin, or a Fiddle on your team, or against an Naut, WW, Garen, Aatrox, or Viktor. I was 3 / 5 / 35 with a double kill.
