I just realized that the rope tying loot bags shut is a different color depending on what type of loot is inside of it. I was just killing pigs to skin and not opening any bags since it's either ham or soda bread (white rope). Then I noticed one with a green rope so I opened it and found a Copper Hand Axe (fine axe, green name). Either my drops have been so terrible for me to not notice, or it's such a small graphic I was blind lol.
Any other neat little things like that I may have missed along the way so far?
