I'm not sure if anyone has mentioned this before (I don't feel like searching through the forums) but there seems to be a minor bug in the mini map.
I like to use the mouse wheel to zoom in and on the mini map. But, when I zoom from the widest to the second largest zoom view, all the influence overlay disapears off the map! When I zoom even tighter then go back to the second level of zoom again, it reappears.
I'm curious if anyone else has seen this (albeit very minor) bug?
