Is there a limit to the number of colonies you can have? I'm playing as Prussia, now Germany for some years. I have most of my positive SOI regions as colonies or as protectorates but it seems now that I can't add the colony card to any of my protectorates even that I have more than 50 CP in the capital region and more than 40 average CP in the other regions.
And now that we are at it, another question not related. If I declare war on France will I be able to ask for Metz even that it's treated as non-national but I have it in my objectives, I couldn't ask for it in the Franco-Prussian war and I'm not sure if there is a way to claim it.
Thanks.
