Also, I went in the tech room and used Ctrl-Shift-S to see all missions to try and test what you gave me out. However, there's only the GTVA path mission of "Irkalla Passes" available.
FYI, I remember when I first beat this campaign a couple years ago, the GTVA path of "Irkalla Passes" worked fine...it's only the ISF path version that has this trouble for me. Honestly, I like the GTVA path a little better so if you can't get the ISF path fixed it's not a huge problem. I do appreciate the effort you're putting into this though. Thanks.
