Stop the map from spinning on an iPhone

The map spins like crazy one direction while the points spin in another direction. I'm getting complaints from customers that the map is upside down (but they must have touched the screen in a way that makes it spin.) I can repro the bug I try to zoom in on a point using two fingers on the screen. Sometime the map just spins and spins! Sometimes it just spins a little making the points out of sync with the map. I do use an overlay picture of a floor plan for the points, and this is what is spinning. Please fix! I have screenshots and videos but the attachment feature is rejecting even a small jpg file.
