Crushbone belt quest
 

I've been turning in belts and every 8 or so belts I get kicked from the server. When I try to reconnect it says that my IP is temporarily blocked.

Is this a bug with the quest? Someone might want to look into it.

You will crash if you try to equip or move items while you have quest item rewards queued up on your cursor, I believe.

I stopped crashing on that quest when I was mindful of that.

The temp block is nothing to worry about. Its just there to keep people from "boxing" (playing two accounts at the same time on the same server)
Just wait patiently and you can log back in
