Not really a bug but a big annoyance for me, but when you join a host the loading screen shows a rotating icon. Somewhere during the loading this rotating icon stops rotating for a while, and since the load time is pretty long it starts to feel like the game froze. So is it possible to add more information to the loadingscreen as in a progressbar?
The same thing counts for starting a server, the time the screen freezes on the menu is just too long.
So in short, please keep something moving or changing on screen to show the game is still running
