Most of my friends are on NW, and he deleted all my friends on NW. He might have also done more than that, i'm still figuring it out. Its a warning to all the people i have on my Steam since most of them play NW and have an FSE account. Also i don't want to spend the time remembering who i had as a friend on Steam, so if they want to be re-added this is my way of telling them to msg me.
