Kennen Kalista bug (also have noticed on a few other champs)

Idk what we have to do to get attention but my duo partner and I have been trying to get a bug noticed for a while now. And its not a minor one like zac walking through the air....i kinda like it leave lol....no if you play Kalista Kennen bot, a combo that is very straigh forward, there is a massive bug with the ulti combo. We have tested this multiple times and it continues to always happen in our games and we have reported it. If you bond with kalista as kennen, then you cant engage properly because when you shoot yourself in on her ult, the bug will literally place you back either exactly where you were when she puls you in, or it will place you two times his auto range away. making the engage absolutely pointless.

Look I know the tech guys over there are always busy and thats fine, but you just attempted to buff Kalista back to viablity and this bug really puts a massive damp in her. Just test it out. Play a game with kennen kalista bot and watch her ulti just get all f***ed and ruin the engage. YOU HAVE TO HIT A CHAMP. It wont happen if you land elsewhere
