Sadly, that happens. We use image overlay and exports off ESPG 4326 and tweaked the hell out of the coords until it worked. Even then there are still issues - which is why we're about 100m shorter than the real city. The overlays match perfectly, but in reality distances are always a few meters off across a large stretch. OSM imports broke completely, so I just ended up doing all the roads by hand with the maps on a second monitor.
