Cutting up a fur coat gave me 18 leather, but it took only 10 pelts to make, and a fur hat took 3 pelts and gave 4 leather.
On the other hand, cutting pelts directly gives only 1 for 1.
Maybe it’s a feature but I figured that it was probably an error.
Also, turrets can’t see shit in the dark, making them mostly decorative, as you can easily destroy them with rocks during the night.
Arrows can’t be fired (or thrown, for that matter) the same way rocks are thrown, leading to some strange situations, like seeing an enemy (like a turret or a smoker zombie) but being unable to shoot him with a bow because there is a bit of darkness or smoke in between, but being able to throw rocks at him.
After some testing on squirrels, it appears that, the way arrows are treated, you can throw them by hand and still do a fairly high amount of damage (26 and 29 with critical hits). Bullets however work fine and do almost no damage when thrown.
(This gives me an idea for a mod… capturing squirrels and rabbits with traps and doing some !SCIENCE! down in the shelter basement… muahahaHAHAHA)
