The issue of dragging magazines from the rifle into your backpack and the mag disappearing is still happening at a 100% fail rate.

Just tested with the new update. The first magazine I reloaded disappeared. It was a full magazine. I then fired my gun. Several reloads are now working fine. However, the first reload if you do not fire still disappears.

I'm seeing reports on Discord of players using dupe exploits in the prof branch with the mag fix. Can anyone confirm this?

This is not resolved as of version 2.18
