I was not able to pick up ammo. Went to the car, opened trunk and there was a sweater with buckshots in it. Tried to take them with option "TAKE" - didn't work. Trade to pull them with a cursor in inventory - didn't work. Tried to take them in hands - didn't work. So I tried to split bullets, because in previous (0.60) patch you were able to get bullets in your inventory by splitting them. It worked kinda, but bullets splitted but only in sweaters invetory. Splited on more time, some bullets showed up in truck.
Tried to split bullet from the trunk. Option "split" worked like for infinite. I was able to split buckshots how much I wanted. My drybag was full with buckshots, but every of them was saying "0". Basically I had full drybag with shotgun bullet shells.
