Double Attack Bug with Spearfield

This bug has been around since Dawn of the Hunt. Spearfield double attacks at times and believe I figured out what is causing the issue

It seems to be happening when you have movement on Left Click, are holding down movement, use Spearfield and are targeting an enemy directly

It doesn't double attack when you let go of movement and use the skill, whether you're targeting an enemy or not. It also doesn't double attack when you're holding movement and target a general area and use the skill


Cheers

Ran into this as well without left click bound to spearfield (I have it on E per testing). Same test case though, try to move while using spearfield and directly targeting a monster.
