If Panda flurry's someone whilst they are in succubus' ulti, they are pushed out of the two wings around them from succubus' hold; but they are still disabled, and the wings stay where they are. It's a graphics bug, the wings should move with the player or it doesn't really make sense and looks a bit strange.
Panda's flurry is only one example of this, I presume there are probably more possibilities of people getting pushed around whilst in succ ulti and they probs do the same thing
Bug confirmed. This can happen with other displacement spells/items. If the effect pushes the target out of the range of the hold. The effect is taken off.
