Actually that wall in the flower shop was made impassable at one point (with the use of Region Tiles), and I think during one of my map-fixing iterations, I didn't remember why I marked those walls a specific region, so I removed it, which lead to what you saw in the game. Then when I tried to fix, I made all the vines impassable, leading to the current issue. lol
I just changed everything back to the way it was. I'm still working on more dialog events, and I want to play through the game a bit before I upload a new version.
