I've been having this trouble some time now, and I don't know how to fix it. When I press the new list button, I don't always get all the servers, sometimes -1, sometimes 43 sometimes 149.
When I have the full server list, getting all the servers on the list is not possible, sometimes I don't even get any servers. I'm on linux, ubuntu, somehow this only seems to affect it, and not my windows machines. Any solution to this? And is this a known problem?
