This issue should now be resolved. Thanks for your patience while we worked through this!
Well, I had two server disconnects AFTER your post, one disconnected me in the STF Infected, but we weren't far into it.
However, a disconnect after a stalled loading screen at the end of the ground portion of the STF Khitomer Accord caused my team to lose ALL progress on the ground - we were all bounced back to the Vega System, and so we lost over an hour of our time and effort.
Uh, dynamic patching? Is that new tech or did I just miss the files downloading in the launcher? If the first is the case: if it changes something, could we still get "release notes" for these? My guess is you changed the voice over in "What lies beneath" to play faster (and some more things, I think), but I wouldn't have noticed if I didn't play it again.
EDIT: Ah, nevermind, I did it again, and the speed of playback changed again too. Weird.
