They are not disappearing from the list. I can be watching it and I am pending and then I am not. Ping is very good in general, and my desk top is hardwired and on wireless.
Any way of adding a notification to show that you were removed from the group. At least then I would know not to requeue. I was pending in more than 100 groups last week that this happened. All of which I was qualified for.
Maybe people just hate fury warriors that much. :)
