[Error] Stat inheritance

[Joobs]

I shot and killed a German with my revolver and instantly unlocked: Kills Silver, Kills Gold, Firing the Gats Bronze, Silver, AND Gold, Fix Bayonets Bronze, and Unhatched Bronze.

I hardly ever use mg and I certainly haven't killed more than 100 people so far, let alone with any sort of machine gun. I've never popped a guy hanging out of his tank, and I've certainly never used the mauser/nagant enough to kill 5 people with the bayonet.

In the process of this, I also somehow instantly gained 23 honor levels, and leveled up 3 kits by one level, one of the kits I've never even used for longer than a minute (Assault). I also leveled up several German weapons when I've only played the Germans on one occasion. The mauser was even all the way up to lvl 24 and had 240 kills.

Did I somehow inherit the person's stats? This is very upsetting since I wanted to achieve all of this on my own time and effort. What the heck is going on?
