I don't know if anybody have noticed that.
When playing BR at the Kowboj server, at the beginning of any round, I 'm used to buy a rifle, say Winchester 1866 or Colt Lightning.
Its weapon change sound is triggered from me, and it is normal, but when any of my team mates buy some weapons, I also hear the same weapon change sound as the one I just buy.
Then I'm just telling myself "Hey, everyone mimic me by buying the same weapon ".
Problem is that it is totally false. I have checked the weapon they just buy and in most case, it is a shotgun, say Remington 12 Gauge.
I don't know if it also happens in other gametype. I have to check.
