OK, I think I got it. Thanks for thorough report! It turns out it was some leftover code in an event that I changed years ago. I think the reason no one ran into the issue was because you have to avoid talking to Jade after Danica's spanking. Avoiding her locks out an event that lets you play with her butt. Heh.
I wasn't sure what the best way to fix this for you was, so first I'm going to try sending you the updated file here. I don't know how itch will respond to me linking the fix right here, but if all goes well, you can just drop it into the www/data folder and replace Map004.
Hope this works out, and thanks again for playing!
