Ornn Ultimate Bug in ARAM

[GAMEPLAY] Ornn Ultimate Does not work properly in ARAM (skip to 0:32 seconds for first incident; also at 2:09)

On Ornn in an ARAM match, every single cast of the ultimate was messed up. Pressing R should spawn the ram far away, running towards Ornn. Instead, it spawned the ram on top of Ornn and ran past him, very quickly. The window for recast was available briefly and some of the ram's particle effects seemed to move towards him, but could not be re-directed through R recast. The second time, although the ram came back the way it was supposed to after initially speeding right past Ornn and spawning on him, the recast window elapsed before the ram got to Ornn.

Not sure if it is reproducible; I just know that it happened every time Ornn ultimate was used in that ARAM game. Lacking a huge part of his kit due to this bug, Ornn felt pretty useless in ARAM and it cost us the game.

(I thought perhaps something about the PBE Ornn bugs could be related this bug, but that doesn't make sense; this occurred on the live servers.) Game history: https://matchhistory.na.leagueoflegends.com/en/#match-details/NA1/2904492605/219209161?tab=overview
