The errors should be fixed now, I've updated the link. When I played, I managed to beat the mission on medium only losing one wingman this time around. Hopefully, that should take of that one difficult part. I spaced the two wings out to give Alpha more time to deal with each one.
As to the Return to Base directive text, I just like seeing it blink completed in my missions. It gives me the feeling of actually finishing the mission, rather than simply seeing the directive in the list. If its a big issue for the campaign I'll change it, I just thought I would state my reasons for having the text show completed.
Also, a rather important question if anyone is listening, why is it I have music in retail FS2, but not in SCP? I'm begining to wonder if my new CD3 I downloaded didn't install the sound VP correctly. I can't open it in VP viewer for some strange reason.
