something similar happened to me on my first visit to Yavin. I hit the switch for the last airlock, then the screen went black and I heard the rodian say something like, "good game. would you like to try another?" The words appeared on the bottom and I was able to select a response. once we were done talking, I couldn't do anything. I loaded my game and worked on completing a planet's missions. The next time I tried it worked. I don't know what fixed it. Maybe it was because I upgraded my characters or had different characters with me.
I support "No Child Left Standing
I have Attention Surplus Disorder.
