One of the (several) bugs included in Battlefield 2042 was an issue involving the M44 sidearm. Prior to today's release of Update #3, the gun had a very odd issue with how reloading was handled.
At release, a reload of the gun when empty would only reload five rounds. The problem is, there are six rounds in the chamber. You can see it during the reload animation. The gun is supposed to have six rounds and you have 18 rounds...
