Yesterday it happened twice that I skinned a Red Deer with a Machete (Badly Damaged I guess) and received some meat with - XX% value?
Don't know if it is because of the Machete always, or just because it was badly damaged, as after the second time the Machete was ruined and I couldn't skin it further...
Have it on Video on Minute 45:30
