After experiencing some problems with my own campaign "GTI Untold Sorties" (see related thread for details), I've gone back to playing the Port for a while, also to see what's new. I've already found a few errors, the most blatant of which is the presence of shielding on your fellow Valkyries in the mission where you capture McCarthy.
In addition, I believe its during the command briefing when you're told about the emergence of the HoL (though I could be wrong), who ever was writing it must have accidentally used quotation marks, because part of one stage is missing.
Thirdly, in the first mission you get to fly the Hercules, the mission briefing at one point has two icons for the Galatea.
I'll keep sending things in as I find them.
Later!
Addition:
I was recently playing "Playing Judas" (where you fly the captured Dragon & scan all of those ships & cargo), and encountered a problem. The way the mission is supposed to go, once the Lucifer arrives, and you complete your scans, you are ordered to enter the destroyer's docking bay. Once you get to them, a wing of Manticores is launched, you are discovered, and ordered to withdraw. This is accomplished by positioning waypoints that correspond to the destroyer's docking bay once it comes to a stop, and if you get within 200 m of it, the Manticores are launched. It seems however, that either the Lucifer has been accidentally repositioned (or re-oriented), or the waypoints are way off. I edited the locations of they waypoints as best as I could remember (one of the Shivan sentries was right next to the docking bay), but I couldn't get it right. Also, one of the docking bay waypoints was labelled "Bat" instead of "Bay"... just a minor problem.
Later!
