Heh, oh dear, I was afraid this might happen. I finally ran into a bug that might actually be classed as major - as in the game softlocked on me. That is, my controls don't work, the event won't continue properly, Aerith and Barret are just kind of staring awkwardly at the camera, Cloud is mostly stuck offscreen - and Tifa shuffles around a bit on occasion, but otherwise nothing is happening, and nothing seems able to happen from here. I'm at Gold Saucer - and I got stuck in the event where the party is supposed to split up so you can meet Cait Sith (at least in vanilla, but I'm guessing it wouldn't have changed in this mod). Let me see if I can upload a screenshot of what I'm looking at right now, in case that might help...
...There we go! Yes, see where poor Cloud is? Here's what I did: I bought the Gold Ticket. I left as soon as I heard about the quick travel feature, to see if and how it worked - and it does indeed work. Unfortunately, it works too early - I was able to hop to Squares without actually using this hub area first. When I finally came to this area (by accident, actually, I wanted to explore every Square before committing to advancing the plot) - Cloud was briefly hopping out of the hole he should have - but then the camera suddenly jerked over to the right, showing Barret and Tifa and the rest walking in, while I was able to control Cloud again - briefly. I couldn't take the bottom right exit, nor could I leave any other way, and Cloud made no attempt to snap back to where he was expected to be - Aerith walked towards the screen...and that was it. Game's stuck. Music keeps playing, occasional blinking, but that's it. Can't progress, gonna have to reset. So since I got stuck in this situation - I thought that it might be worth reporting. I also hope the image isn't too big or anything - I can resize it or just link to it rather than having it display in my post if need be. But yeah, this is what happened - and considering it caused the game to lock up on me like this, I thought it was definitely of high enough priority for sure to report to you now.
Oh, and yes, I tried that program you mentioned - worked like a charm, told me I missed my chance for Shinra Betas, I am sad now. (The recurring Scorp seems like it should have dropped it, at least according to the spreadsheet - I'm guessing the fact that I stole from it, though, interfered with the drop, and that's why I lost it, and never managed to pick up a single one. Damn! I did it to myself, though, admittedly, not being as thorough as I thought with Steals/Morphs in the Shinra HQ building.)
