The math for converting from the isometric tile space to world space was slightly off. I presume (Height - 1) was the original approach for centering the Vector2 on the tile, but it was causing the x coordinate to be off by 1. For worldY, I add an additional yOffset to center it, but it could be removed to set the point to the top left of the tile.
Here's a couple of images of the differences. The blue squares are walls, the orange ones are open tiles.
