I cannot find any mention in the manual of the meaning of flashing red regions.
Selecting the Strategic Cities button above the minimap shows my regions (Caesar) in red - but some are flashing red and I don't understand why. They are under my control and have been for some time (some for my whole game so far) and loyalty is all in my favour - sometimes (often) 100%
So - what is the meaning of the flashing red and why isn't it mentioned in the manual (and if it is - please feel free to enlighten me because I've searched on a load of criteria and none of the entried that came up mentioned anything about this flashing red region).
Fantastic game by the way. By far the best of the ones I've had. Very immersive - and this in an era that I have no idea about!
