Rak'Sai Bug!

Yesterday I tried a couple games playing Rek'Sai and I found a pretty bad bug with her; I didn't have time to test extensively but here's what happened:

when you are burrowed and get knocked up, you stay burrowed, but when the knockup ends you are unable to move and/or unborrow by right-clicking enemies. You are stuck there and can't move or attack. Flashing away makes you go back to working normally.

Since I only played a couple games, I am not sure if other types of CC cause this, but both times it happened it was because I got knocked up while burrowed. Please look into this and tell me if this is known/happens to anyone else/will be fixed any time soon.

Thanks and I hope this helps.
