I used to frequently have this problem, and now I don't.
Contrary to most people, who say that relogging helps and stuff, I find the longer I stay in game, the less lag I get, the less d/c's I get, etc. o-o;
The only recent one I got was at the KQ loading screen ... I couldn't get it, relogged, and was back in eld >O<
But it really shouldn't happen so frequently ...
PS. Villi, your siggy scares me. Especially the second pic o-o;
