Hadn't posted this earlier, since I thought it wasn't INNO, but since it has now corrected itself, I assume it was tweaked and silently rolled out.
The extra zoom (out) modification had, I think, treated the interface as part of the city. When I pinched on my glidepad to zoom in closer to my city, the interface elements on the edges of the screen would also enlarge and stay on the edge of the map. To get to the quest givers when zoomed in, for example, I would have to scroll to the left edge of my map to access them.
Now, when I pinch on my glidepad to zoom in closer to my city, the interface elements on the edge of the screen stay the same size and stay pinned to the edges of my screen while the city enlarges. II can scroll around my city and interfaces elements are always accessible in a single scale; for example, the quest givers are always on the left edge of my screen.
