Hi for some time, all servers are running under sleepers.
My question, therefore, is why only some of the servers in the list are described as sleepers?
Because of the current servers hwili no description sleepers by many players are treated as no sleepers for what awaits them sometimes nice surprise.
I personally play the EU - Central Europe by PlayRust.EU and additional server is running a version of the EU - Central Europe - Sleepers by PlayRust.EU, as it turns out both are sleepers, so I consider it to be described as sleepers all servers or on these no description disable the server function.
