I read somewhere that it’s development after autonomy that is counted for dynasty changes, so if you have a lot of high autonomy provinces they’ll beat you.

Prestige + what it says in the tooltip isn't often accurate.

Spreading your dynasty has to do with effective development, not development. It is development factored by local autonomy, a stat which is hidden but very important.

Edit: This has nothing to do with prestige, don't comment if you don't know. @atwix made all of that clear enough.

Prestige has nothing to do with it. Hasn't for a long time. It's autonomy-modified development. Atwix guide covers it all.

Also you can check your autonomy modified development in the institutions screen.

Prestige?

mine is 82, while castille has 64

Go to the institutions screen and check your development after autonomy. If Castile has higher development after autonomy that is why they are getting a heir on the throne and not you. Prestige plays nothing in landing an heir on a throne or not.
