Great Weapon Fighter- Wicked Strike Bug (PVE)

gadget

Hello. I've been experiencing an issue with the Great Weapon Fighter's Wicked Strike ever since the Storm King's Thunder update. There seems to be some kind of stutter with the animation on the second or third swing of the attack. Instead of a smooth 1-2-3 succession of attacks, the character will only attack once or twice and then get stuck repeating animations of the attack without actually hitting anything. I've had this happen both while attacking normally and while Unstoppable is active.
