When engaging in melee combat with the Pickaxe, Farming Hoe or Shovel, the characters left hand/wrist can become very stretched, not only does this look weird but in some cases will block your ADS view after swapping to a firearm.
In order to reproduce this consistently I swing the melee weapon while looking over the left/right shoulder of an infected, in some cases you can hit them even when they aren't on your screen, my theory is that the melee 'lock-on' system, in combination with the animations of these weapons, is causing issues with the character when you try to melee without looking directly at the target - but I'm not a game dev so I'm probably very wrong :)
I tried to reproduce the issue with other 2 handed weapons like the Splitting Axe, Firefighter Axe and Sledgehammer but was unable to (I'm assuming this is because they use different animations)
I set the severity of this issue to minor simply because the player can fix this issue in-game by emptying their hand slot, however I can imagine if this happens with very unfortunate timing, this issue could disrupt a PvP encounter and cause the player to die.
