Well crap. Wish I could have gotten these in today's update. Glad you reported them though. That stuck Hyena issue is an easy fix, got it patched now. The others I'll come back to tomorrow on a fresh brain, but yes, can confirm that you can leave the plaza after talking to the clerk, without doing the scene. I have no idea why I did the trigger like that when it CLEARLY should be after the scene is finished. Ugh. This is why I'm grateful for these reports though: it's hard to see your own blindspots.
And yes, I still want to know about those wall issues, even if it doesn't really allow for cheating. Still sloppy stuff that needs to be corrected.
Edit: Got the porn shop/plaza trigger fixed now. I THINK. On the kitsune, which one do you mean? If you're talking about the Mint and Taffy exchange as they're hauling him, that explicitly has handlers for all the wardrobe items currently available, so you should be getting something appropriate.
