Zoom back to previous zoom , after auto zooming to for example Diplomacy, Religion, or Civics screen and thus out to the grey map.
This is annoying since I always have to zoom back to where I prefer the camera to be, and this happens all the time (every single turn) so is quite annoying.
If the game absolutely have to take control of the camera, at the very least zoom back to where one was when finished. Or put an option in for turning on/off automatic zooming.
