When "zoom in" control is set to a key combination other than the scroll wheel, and that key is pressed while viewing the map in a saved game, the game does not resolve to showing actual activity (in regions where you should have vision due to radars), instead only giving the map thumbnail view.
I would imagine this is simply a case of a condition on "scroll wheel pressed" needing to be changed to "zoom key pressed".
Thanks for the report. And thank you for including the log.
What you want to rebind is controls for "Alternative zoom"
I didn't like the default behavior of automatically zooming into/out of game view, so I added the extra zooming controls in a way that preserved the default behavior, while allowed me to rebind controls in a way that zooming in map switches to game view only when I explicitly want to. So that is why there is "Zoom" and "Alternative zoom" bindings ... which might have been mistake as this is not the first time somebody got confused by it.
