Getting stunned/displaced while under black shield (?)
I was playing Morgana just now and there was a Trundle player on the enemy team.
Several times during the game I was knocked airborne/briefly stunned/displaced by Pillar despite having Black Shield on me. This is a form of disable/displace that should not bypass Black Shield ... it is a clear bug and not intended to function in this manner.
