Twice now, I've completed a side quest in Fallout: New Vegas, received a unique weapon, given that weapon to one of my companions and then had the weapon disappear completely from the game. Is there a way to get these weapons back? I'm playing the 360 version, so console shenanigans won't work.
I have a theory about why this is happening, but I haven't been able to prove it. I'm guessing the weapon condition drops to zero while the companion is using it. When my own items break down in use, they just get grayed-out in the Pip-Boy screen, but they can still be repaired or transferred to a container. Maybe the companion inventories can't handle such unusable items?
