At range smaller than max range kalista slides back into original position. At max attack range kalista completely locks out during that spin meaning

Heh, I was just about to download some screen recording software to submit this bug myself. It is making not play as expected, and needs fixing ASAP, She shouldn't be weak because of non-functioning mechanics.
