I'm not sure if that's a bug, or if it's intended, but I'm gonna report it anyway:
I was playing with the class "Assassin with pistol". Because I wanted the pistol to be the 1st weapon in my inventory (so that it comes first when I use the mouse-wheel), I dropped both weapons and then I picked up the pistol, and afterwards the dagger. The problem is, when the pistol is dropped, I cannot pick up the cartridges anymore (I cannot even see them). Is there a way to fix this?
Notice that the cartridges can be seen/picked up normally if the person dies while holding the pistol.
