I heard many players lost many of their friends, sometimes even more than 50% of the list. In my case, I lost 525 and I had 995 =/

It seems that only old/inactive friends had disappeared and, for example, a player called Boss (was on my list) is on PVE kills LB, and if we try to add him says "player does not exist" hummm ..I believe it's not the only case like this.

Can we know what's going on STS?
