So pretty much for the last 6 months there has been a glitch going around where when someone would attempt to kill somoene while using full auto the bullets would do absoletely nothing, they pretty much come out of the gun and dissapear.

It used to not be a big problem but for the past month 1 out of every 4 firefights I get into it happens. I push somebody holding a building and spray my entire mag into them and nothing happens and I die. It has happened on multiple servers and I've talked to 5 other people and they all have said it has happened to them atleast three times.

It's a very bad bug that leads to hours of time being wasted.
