when can i annex vassals and when not? (need to know for the ryukyu-challenge)

[Windar]

Im playing the ryukyu-challenge (doing good so far, conquered whole india), but it drives me crazy, because i dont understand when annexation is possible and when not.

ok, here we have 3 situations, every single one out of core-distance.
1. Right at the start i can vassal nepal and 10 years later i can annex it. (surprises me it works)
2. That doesnt work for Gujarat. I have to vassal gujarat and Kandesh right next to it. Then I can annex them. (thats the way i think it should be)
3. But in Africa that doesnt work neither. I conquered two small countries (Benin and Hausa) next to each other, made them my vassals, but i cant annex them. (why?)

remember, all of the countries here were out of core-distance, but we have 3 different results. Can anyone please explain me how it works?

ps: im playing eu4 without any dlc or mods.
pps: plz dont tell me i should go within the core-distance, im trying to safe some time and make big jumps to the west for the westernization.

1) doesn't make sense to me unless there's an issue with connectivity through the wasteland province, lakes, etc. putting it within your coring range

The difference between 2 and 3 is due to being on a different continent. Non-overseas territory adjacent to a vassal can be cored but overseas territory must be directly within your coring range and you can't annex a vassal if you can't core their capital.

You can only integrate a vassal if and of their provinces are within your coring range.

If a province borders one of your vassals in your home continent (in your case, Asia) then it counts are corable regardless of distance.

different continent, ok that makes sense. thank you guys.

so, the thing with nepal seems like a bug. btw, its also the same with Kachar. (probably even more countries, but i didnt test them all.)
Nepal and Kachar are often allied and i always could annex both of them without a vassal connecting to them.

Definitely a bug.

If you need to annex a vassal, sell it one of your cheapest cores that borders another of your cores. That will bring it within range.
