I encountered a friendly NPC in the road close to my base, I right clicked him and told him to "join me!" He accompanied me back to my base and took a rifle and pistol from a box and I pressed G to make a guard spot for him to stand guard at my base. I started to get a performance drop at this point and went out to loot some of the zombies he was mowing down. Whenever he kills zombies they drop what I'm assuming is a duplicate of every item in his inventory. A rifle, 1 rifle mag, bullets, pistol, a key ring with his name, etc etc. Idk if it means anything but all the guns have different durability so it's not an exact copy of the one he has on him.

There's no errors popping up.
