Hi Sega.
Thank you so much for taking the time to fix the IRO for me. I'll be testing it right now.
Here is a link to my save file.
Save 2 is right before the death scene. Save 3 is where I used Black Chocobo to try to add her, but it didn't work (and I'll be on the highwind shortly to test the debug NPC).

Edit2: This is my first playthrough of NT, so I'm assuming there may be criteria to her being usable again. Anyway, I tried through again with the default scene. That went through normally. I still don't see Aerith, so I'm going to play around and see if there is any unlock criterion.
Edit3: I tried the original IRO again to see if I could maybe get a different party comp to trigger the scene to switch, no dice switching Vincent for Tifa. I'm going to try once more switching out Yuffie.
Edit4: Yuffie was breaking it! I took out Jenova with Cid and Tifa and it progressed to the next scene and I can see Aerith laying on a bed which I have not seen yet. Aerith is now in the PHS screen immediately. God damn Yuffie. Don't ask me why that worked, but it did.
