Heavy Shot Animation Bug During Wanderer's Minuet (BRD)

Character: Xevious Vespre
World: Adamantoise

I've noticed that when Wanderer's Minuet is active on BRD and consecutively casting Heavy Shot, there is an animation bug such that your character is pulling on air rather than the bow string.

It only seems to occur after the first Heavy Shot in any string of consecutive Heavy Shots. Here is what it looks like:

Notice there is significant distance between the character's pulling hand and the bowstring and arrow.
