From Steam: Colonisation works only on directly controled provinces

[TypicalCrusader]

2a. I can 'colonize' counties that don't belong to me. I don't believe they stay colonized because colonization seems to auto-stop when the county owner is of a foreign culture.

2b. The colonization Title Decision only appears when I directly control the county. This means that I have to periodically and manually look for counties in my realm to colonize since my vassals often conquer on their own.
