Gray Boars should have their health reduced. 500 health is way too much for an enemy as common as the boars, even if they aren’t permanent.
Wdym? They are permanent?
They don’t despawn on their own, but they eventually stop respawning when killed after a certain story event.
Oh right I forgot that I didn't get to that story event because I only got that far in 0.8.0. That's why I thought they kept respawning even after the event. My bad.
