Hey, I searched through the forum and to my surprise I didn't find similar reports yet, I can't be the only one though. Maybe it's already a known bug. First time I saw it happening was in Firestorm mod, not any other mod before.
When picking up a weapon (happened with pistols, a FG42 and other models I can't remember), although I picked up the ammo, I:

1. Either can't load the weapon with bullets (it says no ammo), although the correct ammo is being picked up and showing up in the inventory
2. I can only reload 1 bullet by 1, means I need to keep on press reloading to add 1 bullet by 1 into the magazine (saw it with FG42)
3. I can't pick up any ammo because it says ammo is full, although the inventory shows there is 0 ammo of this type

I will try to add a video when I come across it again.

Just FYI.
