Durning the mission, I was taking a friend through it for the first time. The first bug he encountered was the no crouch bug. Remapping his buttons, we were able to proceed with the mission. The 2nd bug was him getting disconnected when we opened I believe the first hidden chest behind the laser barriers. His primary was full, so it dropped as an engrams on the floor. He deleted a blue primary, picked up the engram. To his dismay, the weapon he got was Disparity with a desperado and outlaw perk combo (nice) I think he got error code Weasel. He logged in and the blue he dismantled was back and the Disparity was gone. He checked his post master, Nada. I checked my post master as I was full on primary weapons, and I'm sure it was his gun in my post master! Exact some roles. I went to claim it and my game crashed. Error code Weasel. I logged in again and pulled it from my post master via the companion app. It's a beast of a gun, but I wish I could give it back to my friend... Not sure if my ne has had a bug like this before.
