Morgana Ult stuns enemy in Zhonya
I just played my last game and when I Zhonya to avoid Morg's ult.
I got stunned, in my golden form. This is BS.
(Yes, the Zhonya effect was still on when she stuns me.)
I reproduced the situation and recorded it, here is the video link:
Notice how even when Zhonya ended I still couldn't move.
