Oh, and a minor bug (wasn't worth writing an email over really) is that if you equip a perk to change your max ammo, it only refill your ammo once you leave a region. Eg, I have 30 max ammo, I equip a +10 ammo perk. I enter a new chunk right away and still only have 30 ammo, when I leave it goes up to 40 ammo.
