It all depends. I would rely quite a bit on breaking down trash bags and the like that are outside on the streets to get plastic for steel arrows/bolts - or for some other recipe (usually in a last-minute panic to prep for horde night

). Has the occurrence of plastic in loot been balanced to cover the removal of this harvestable resource from trash bags and other random decor blocks? If there were a recipe to craft your own scrap polymers in the chem station, that would be a good option.
Same applies for the feathers to make stone/iron arrows/bolts - I would usually take the time to break down the nests to get more fathers out of them. Are there going to be more 'lootable' feathers in the nests to compensate for this loss of a harvestable resource?
Or... will skilling up in Archery increase the amount of feathers you can loot/harvest from nests/vultures/chickens?
