I believe the patch notes said that 10 weapon kills would earn you a ribbon. I made 13 kills with the NS-11C during my lunch break and didn't receive a ribbon. Do they vary by weapon type or is it simply bugged?
Well ist seems to be a bit Buggy at the Moment but I am sure they will fix it. I realy like these ribbons thou...
They were working for me, some of my friends didn't get points, some gained 1000 xp per ribbon. It's buggy as hell.
