On Xbox one - after leaving party chat, and also sometimes after prolonged play- sounds degrades and its as if someone is blowing a dog whistle. Have to restart game to remove annoying sound. Weapon errors - certain guns the upgrading texts are wrong - off the top of my mind, icebreaker has three upgrade options that are identical - one purplrle machine gun has one upgrade option that does the opposite to the graphic bars above. Plus a few others I have noticed. Sometimes when shooting - it looks like you have a perfectly clean shot but bullet doesnt hit target - usually when shooting through gaps - almost as if bullet proof glass is blocking fire.
