[GAMEPLAY] QSS effect from nowhere

Just had a strange bug in aram. I've played Morgana and Urgot ulted me. Right before the end of his channeling somehow ult was canceled (suppression was removed, we didn't swap positions) and I had a QSS animation on me, though I didn't have QSS and no one in my team had Mikael's Crucible. From my teammates only Caitlyn was near, and she wasn't in range to drop trap under Urgot.
