At last I've finished the campaign! (I've got to hand it to you: what an ending! Refreshing, to say the least.) Anyway, on with the last few complaints/suggestions...
In Hmsk-C5.fs2 ("Pitched Battle") and Hmsk-D2.fs2 ("Blind Man's Bluff") I think you have some more premature 'Depart' directives. Easily fixed, and I'm sure with my last warnings, you've probably already found these ones. There could be more, but I was extra careful to jump out only after all friendly ships had departed.
In Hmsk-D6.fs2 ("The Road to Hell..."), the 'battle' between the Khufu and the Kintyre looks rather strangesince they're not shooting at wach other. Perhaps you should make one of the corvettes part of the 'neutral' team so they shoot at each other. Also assign to each ship the ship-guardian flag. Related to this: is it intentional for the Kintyre to shoot its beam cannons at the Custodian? Afterall, the Kintyre supposed to be fighting the Khufu.
In Hmsk-D7.fs2 ("...is paved with good intentions.") this happened: When the Geryon jumps in, I made an effort to destroy its forward two beam cannons. I did this, so when the time came for the Custodian to be disabled, all you got was the Custodian suddeny becoming disabled. I suspect you intended for the Geryon to fire its beam cannons at the Custodian, but of course this could not happen once those cannons were destroyed. I guess all you need to do to fix this is to make an event which repairs the forward beam cannons just before they fire.
Well, that's it for me! Sorry for my nagging and prodding, I hope I have not been too cruel.
