I was going through the klingon ultimate weapon quest for the 2nd time (via sharequest) and was able to complete the ground combat at the space station, but when i went to transiton back to space after talking to the NPC at the end it goes to the loading screen for apx 3-5 mins and then goes to the login screen. I've tried 2 additional times via logging back in and selecting the button @ the bottom right, "Continue: among the debris"
Did you ever get an answer? I came across this while trying to find why the Klingon after the ground part never de-cloaks. I could fly around all night and he still doesn't show.
I had left the game for some time while looking for a fix. When unsuccessful, I returned to find the debris field gone. At this point I figured mine as well exit. I exited to Sector Space and noticed that I could continue the mission, I did. When I re-entered, I received the hail from the klingon like the last time, but this time he de-cloaked right in front of me.
