I was playing T&R a while back on the MCC and whenever I'd move into the last outdoor area (with the grav lift), I'd kill those enemies, one dropship would come down, and then nothing, the game wouldn't advance to any of the later groups of enemies. This sounded vaguely familiar, and I tried waiting in different places and going about killing the enemies differently, and when I stopped I didn't save. Today I started back from that save (which it turns out it right at the part where you enter that area anyway) and tried again, same behavior. I think this might have been a pre-existing glitch. Does anyone know anything about this?
