Mission Loading Freezes

[BlitzPig_EL]

Last night both myself and one of the other BlitzPigs experienced the multiplayer mission loading screen freezing at 16%.  I got past it by hitting the escape key a couple times.  Somtimes when this happens I would get a black screen, then it would come back and finish loading.   I was hosting/playing on my own machine.  Once in the mission I was getting 100fps sitting on the runway, and between 140 and 165 (vsync on) in flight.
