everyone was randomly getting sion's W instead of their actualy W in my last game.

yes it even happened to me. i was playing irelia top then all of a sudden i see my top lane opponent (vayne) with a sion shield on her, then i saw udyr having the same form time to time, then it was happening to me. randomly i get sion's w as an ability instead of my irelia's w and i cant use the actual ability instead i get sion's w (and i can pop it) everyone was having this in my last game. Note: there was a sion on the enemy team. Edit: u get the whole shield and the damage.
