i told you...next time invite me op de Meir.

i am not certain, but i believe there are two variables:

the average Cp in your case is given (green area where the card can be played to...!??)

but there is i believe a second variable:

a certain level of development is at least needed for the declaration of colonies.

exactly for the building of Gov.Mansions itself, not sure if this is true for Consulates either and solving your problem

EDIT:

Gov. Mansion:

MinCP = 50
MaxCP = 100
MinDev = 20

*****

Consulate

MinCP = 30
MaxCP = 100
MinDev = 10

38% dev , tracks. by the way that would stop me straight away not after a few turns

Presence of enemy troops triggers this message I believe as well

We need more detailed info on the subject... like for example:
-Which colonial area
-Your CP
-Any other nation CP
-Development level
-Military control
-Your military presence in the region

Then we can comment with more info...

If we cannot find a solution, we will require a saved game in due time.
