Tristana bugs

There's like 2 known bugs to me atm (1 in game bug) 1 of them i found is a skin bug in draft ranked solo/duo that makes me have to reselect my skins every time. I am using the legacy client atm. I have 3 skins and the chromo pack on rocket girl tristana. I generally always use the rocket girl tristana skin with the chromo pack of most dark blue one (says punk at end for every 1 of them i think). The other bug I know is there seems to be a gameplay bug where everytime I w then ult in mid air, it will knock the target back as in the direction before I did w. It can get very annoying when I try to get away and the bug (at least i think it is a bug) is what killed me. You just have to ult while in mid air to reproduce this. A rioter told me to post on this I believe. I'm a tristana main and this issue has been bothering me for a few weeks.
