So one of my opponents territory is entirely in he dark to me and always has been - but I can tell he has an Intel officer by clicking on one of his stations and comparing the circles radius to my own... If my opponent had chosen assasin or pirate then quite rightly I wouldn't know that until I saw his specialist.
This destroys half of the benifit of having an Intel officer to get Intel that others don't know you have...?!?
Likewise my time machine seems aware of gifts made between other players in the dark - specifically combat predictions for the future change when a gift of a general is made to my enemy in the dark... Not much of a surprise to me when the moment a gift is accepted my projections update based on Intel I can't possibly have!
