I have trouble taking crossbow arrows out of zombies' bodies. At first retrieval works for one or two arrows, but after that the option to retrieve it goes away. The arrow still shows up as "ammo crate" when I look at it, but I can't pick it up, even when I'm right next to it and looking right at it, and it's barely even touching the zombie. The 'gear' option goes away when I look from the body to the arrow, so I know the game is recognizing that I'm looking at the arrow (also, the 'ammo crate' thing). However, after the zombie body disappears, there's an arrow left behind which I CAN pick up. And I have also gotten the bug that destroys a partial quiver and takes an arrow out of the full quiver when I'm reloading the crossbow.
