I also got a wrong debrief in
Rebels and Revolutionaries. I definitely killed all platforms, but got the not-all-platforms-destryed debrief. Within-mission jump sequences also seem not to work 100% smooth in that mission, e.g. once the subspace environment disappears one or two seconds after the player ship passed through the exit vortex.
In the tower defence mission the lead indicator is black which is not exactly helpful in space.
Oh, and in the mission where you capture Gavel, his ship's engines repair themselves after he turns friendly. The support ship eventually was able to catch him, but I guess this is not supposed to be.
I also discovered a few more flaws here and there. I don't remember the campaign causing so much trouble when I played it a couple of years ago. Maybe it's something wrong on my end.

Not bugs per se, but:
- In the final mission I think a checkpoint after Epsilon arrives would be convenient.
- I accidentally entered this screencap mode, of which I didn't know it exists, and it took me a while to find out how to get out of it again. Maybe give the player a hint which keys to press to exit again.
