There is a similar client-side visual bug but for attacking, where I see myself holding a swing but upon release it comes out as a different one. I wonder if the process to replicate is the same.
Here are the inputs for the first example on the video below:
- Block left
- Look to right and hold attack, you can't tell visually because block overrides attack
- As I let go of block I look up and over slightly
- Since I never let go of left click it shows an overhead hold when I release block
- Upon release the swing comes from the right
On someone else's screen it shows me holding the same direction that is released.
I think since you never let go of right click you were always holding the same block, but visually saw the wrong one because when you look left after the stagger-from-hit animation plays the game puts up a left block animation.
