My computer's been refusing to wake up from a black screen as of late, so I've been force-rebooting. Thus, messages may have been missed, especially if I'm idle for 1h+. Sorry. Am looking into the problems atm.
 Ah, problem found - I was using an iTunes displayer-screensaver.. but since I updated iTunes and hadn't run it past the welcome messages, it caused the screensaver to die. Stupid screensaver.
