Ornn ult acting weird? Is it bugged?

[RESOLVED?][GAMEPLAY] I just played a match as ornn, and I maybe hit one ult the entire match. Is it just me, or is something really messed up about it right now? I went into practice mode to try it out again, and I could instantly 2nd cast it to work fine, while if I even tried to wait for the ram to get near me to direct it, it would go on cooldown before anything happened. The elemental animation also seemed to lag/hop backwards sometimes. I didn't exactly figure out exactly how to replicate it, but it usually happened if I didn't re ult right away but waited a couple seconds before trying to charge towards the ram (before it got anywhere near me).
