I just noticed something that I find odd and tbh unfair against unofficial servers. They seem always to be at the very end of the list, despite of the sort order.
If I sort the servers based on the ping, which I assume most of us do, they still come after the last, highest pinging official server. Because of this I wasn't even aware of the existence of these servers until I just happened to scroll at the end of the list, to show the amount of servers to my son
I'm pretty sure this has an impact to popularity of these servers, since noone ever sees them at the top of the list when looking for a free server to join.
