I grabbed that from a dead firefighter zombie to cut it up for kevlar but it has no hotkey. That means I can’t do anything with it, including unequip it.

EDIT: I’ve been playing cata for over a year and had no idea that you could hit enter to select an item in your inventory and drop it. When I picked it up again it had a hotkey and everything is fine.
EDIT2: There’s something wrong with the hotkey counter. It says I’m at 69/74 but I’m a lot over that and several things are missing hotkeys.
