Ever since I have installed build 770 I have run into a world of problems, none of which I have managed to fix. The main one is the fact that when I try to join passworded server it just takes ages and then after a minute or so just says "connection failed". Also whenever I try to change my UI the game always freezes and I have to ctrl+alt+delete and close it using task manager. The UI does not change through doing this however which means that the supposed fix for my initial issue cannot be done. Please help, this build has been an absolute nightmare for me.
Assuming you're using a non-standard UI (you didn't actually say), have you tried reverting to the default one via the Launcher -> Advanced option?
