[GAMEPLAY] Rek'sai getting STUCK IN PLACE

I get stuck in place a lot AND unable to unburrow on targets on top of me after being CC'd/Stunned until i actually move around again. After being stunned I would think attack clicking on my target would unburrow me so I can knock-up and begin my combo but often times I am stuck burrowed until i move around which doesn't feel like ur natural instict when playing him. Also can't jump into a nearby tunnel after being cc'd/stunned until you move around. Just noticed in my last game.
