[GAMEPLAY} Sion, Decimating Smash and ultimate elimination

I was playing team builder yesterday and i was solo top against first spell i got was q and at about level 2 i was going to use it as came to attempt a gank and Darius hit me as she unburrowed it canceled out my smash and i was no longer able to use that spell. when i was able to get my ultimate i attempted to use it mid lane and it wouldn't activate. so. i wasnt able to use 2 of the most important spells that sion has. just thought i would let you guys know this.

im not sure if this will work but

1 sion vs darius top lane 2 rek sai unburrow beneath sion 3Darius attack sion and sion wont use smash anymore.

im not 100% sure that will work but this bug happened to me twice.

Edit: BY THE BY the first time this happened to me was on a custom game and i was fighting Garen and i think Kha Zix cant quite remember the details though. but same result. i was unable to use q and r through the whole game.
