I would like to ask what happened to the option SERVER LIST on TeamSpeak?

A week ago, maybe two application servers properly sorting the available eg. By the number of registered users but now sorts as if by IP address and cannot locate the geographical location of the city

for example - the sort for my country. all the servers listed here have a server IP address that starts with the digit 5

for another example. That server have for now 15 online users. They have a region name and his address ip start a digit 37.. and does not appear in the list of servers by the program with " Displaying 100 servers... "

oddly enough even has the appropriate number of users online to qualify in the list of 100 servers.

What's going on? This may be a bug?
