[Gameplay] Rek'Sai has Bugs

Multiple times this has happened to me when playing Rek'Sai. I am burrowed and approaching an enemy with hard CC. I get Annie stunned or fiddle feared for example. For whatever reasons the enemy I want to knockup is still on top of me by the time the CC ends. I attempt to right click and knock them up however Rek'Sai does nothing until I give Rek the command to move someplace on the ground first.

When playing Dominion as Rek'Sai... I was killed by area of effect damage while beginning to use a pre-placced tunnel through a wall. I was unable to use my first revive at all either by keybind or clicking the icon. I respawned about 20 secs later normally. If it helps I the tunnel I died in went through the circular wall above the bottom right capture point. Died near the beginning going from SW to NE
