Illaoi vs Kayle Possible Bug
I found this bug while playing ranked recently. It seems if Illaoi uses her E on Kayle and Kayle tries to ult herself the ult will go to Kayle's copy instead of herself. It could be that the Kayle clicked on the copy instead of using the ult on herself, I'm not exactly sure how her ult works but the enemy Kayle claimed she ulted herself.
