I noticed that enemies will quite often have 2 of the same weapon. For example, if I kill a Raider who has an assault rifle, sometimes he'll drop the assault rifile on the ground, but still also have one in his inventory, allowing me to collect two of them.
It seems unlikely to me that this is the way it was intended to be. I can understand the concept of having a backup weapon, but it's a bit strange when a raider drops something like a sledgehammer, and then has another one on his corpse.
Is this normal, or am I experiencing a bug? Does anyone know of a mod that prevents enemies from having duplicate weapons?
