Hope I'm posting this in the correct thread. This SEEMS to be the Nightmare 7 thread. I need to say that I installed the mod EXACTLY as required with bootleg and all. It works wonderful (& difficult).
I did find a couple bugs with this mod, though.
#1 Junk Shop at Wall Market. Not a big deal, but when I entered there was a .... ghost duplicate of Aeris to the left of the entrance. No graphical glitches on screen or in the menu or otherwise. Can't interact with her, nor does she hinder movement. Similar to seeing her in her church before she disappears, but in Wall Market Junk Shop she doesn't disappear.
#2 in Train yard after climbing up from dealing with Corneo in Wall Market. There is a potion / ether / tent item on top of one of the trains. I assume this is a one time item, unless it was programmed as I found it. I acquired about 30 Ethers, 20 Tents, & maxed out my Potions. It never stopped spamming items, I just got tired of button mashing. I guess this one is better left unfixed!
#3 in Shinra HQ. The room where Jenova was kept. After Seph takes her you check the black room with Holy- and a Midgar Zolom. I found a repeatable crash. Every time I had Steal+ equipped with ANY materia and then used that materia.... crash. I tried Ice and Fire.... crash. Then I purposely tried it with Analyse. Same thing... crash. After that I thought it might be the Steal+. I unequipped it & viola! No crash.
edit: I almost forgot. I always get a crash whenever game over happens, instead of 'new game / continue' screen.
