Issue Summary:
Crude Spears thrown at hogs are not causing damage as intended. Due to reports from players we are also looking into other projectile weapons and creatures.
Workarounds:
Stabbing with a spear repeatedly or attacking with an axe / knife appears to damage as intended.
Giant Crabs and Hogs both shrug off damage from speargun arrows. I normally use those for hunting, and had to craft a spear to use instead when I found that it was taking too much ammo to kill them.
