Whenever I join a Multiplayer server the lobby UI that would allow me to join a squad or team is missing. Without the UI elements I can't even play on the server. Strangely thought the OK still abutton ppears in the bottom right hand corner, and when I press it it starts downloading the data from the server as usual and the UI elements reappear (I still cannot use them though), but as soon as the download finishes an empty text box with an ok button appears and I am disconnected from the server.
I have tried multiple things to fix this such as disconnecting and reconnecting from the server, trying to connect to different servers, and even restarting my client, but nothing has worked. If necessary I may be able to provide screenshots of the problem.
