Missing mission casus belli as Sweden

[caiomarcos]

So I am playing with Sweden and I have the mission "Protect Norway" where it says that since the Kalmar Union is no more, I must make Norway my vassal, when the mission first appeared I checked and there was the option "subjugation casus belli" but now, a few years later, this option is not there anymore. What's going on?

There is a time-limit on those CBs, 5 years I think.

The mission lasts until I cancel it but the casus belli goes away?
