The version you are using. - 1.0.3
What you/the other player were doing when you noticed the bug - Just me
Is it reproducible? If so, how? - Yesh
What you would expect to happen if the bug didn't occur - Join the server without entering the password more than once.
A brief description of the bug - When you try to enter a locked server and the password dialog box comes up, then when you enter the password and check the remember password box it doesnt save the password.(Dunno if this happened in older versions)
