Infernal Diana post-ult glitch

I wish i had had the foresight to provide video footage of this bug for you. Not only was it bizarre, it was also highly amusing. The long and the short of it is that, as diana using the Infernal skin, and with these items: Iceborn Gauntlet Berserker's Greaves (enchantment: Captain) Titanic Hydra Nashor's Tooth Guinsoo's Rageblade Banshee's Veil and the HP-tenacity consumable

i ulted an enemy ezreal who possessed these items: Mercurial Scimitar Blade of The Ruined King Muramana Ionian Boots of Lucidity (enchantment: furor) Mortal Reminder Iceborn Gauntlet

However, instead of jumping to him as my ult is supposed to do, i did not jump and my character became a fireball. My character continued being a fireball for the remainder of the match; during this time i was able to use all abilities successfully including ult, died and respawned, etc, all as a fireball. Being a fireball is very cool (or maybe hot), but having the ult glitch out in such a manner is not cool, and i would be most appreciative if you were to investigate what went wrong and send out a fix. Also, what do you think of my build? pretty neat, huh?

one more thing. on another occasion - and probably this is of more interest to you - i ulted somone who was in a bush, as diana, while outside of the bush, and my ult killed them, did part of the dash particle, etc /but i did not jump to them./ i'm not 100% certain how to reproduce this, but i feel i might as well let you know that it happened because there are probably all sorts of ways that could be abused. Thanks edit: i believe on this second occasion, i was ulting someone over a wall. It was the wall near red, botside. Is it feasible that my ult decided to do the damage portion but didn't let me over the wall?
