By request of eabarry, I'll crosspost from http://answers.ea.com/t5/Battlefield-4/Weird-glitch-after-latest-update-Mantle-30-january/m-p/2269257/highlight/false#M92315 here:
After latest update BF4 is completely broken. You join a server, come to deployment screen, sound plays just like the round has ended and the scoreboard comes up with your unlocks etc, and BF4 does not respond to any HID input at all. You can move mouse and alt+tab out of game, but escape, enter, arrows, mousepresses, consolekey etc does not respond at all.
To devs: I think that you borked some game-state related thingy, as the game just acts like it does when the round has ended (same sound plays just after level has loaded, reacts to no input), but since the game hasn't ended, the transition in the end of the game can't finish which means it can't change back to allowing input again. This is just my speculation as a fellow programmer. Please fix this ASAP! I am not the only one suffering..
