This seems like quite weird glitch. When entering a server with almost full population cap for example 39/40 or 38/40, the server will let me login and the client will load the map. However, the connection to the server doesn't sustain. In fact I won't be able to interact with anything such as inventory or environment. However, 'no response to server' message will not pop up no matter how long wait. The server is still on the list after disconnection.
