Oh wow, my people! Someone directed me to this thread after I was randomly griping about it on my server's Facebook page. I've been getting constant 900002 errors for about a week or a week and a half now, roughly every 30 minutes, but sometimes it'll go upwards of an hour without rearing its ugly head. Wired connection, no packet loss during 900002 error, no other issues with any other games. I've broken a couple high dollar synths because of it.
