Aaah... inheritance... and Gavelkind at that... The way it works is that grandchildren are still in the line of succession, they're just placed after the direct children, which is why they're not your primary heir (as long as you have eligible children that is). But yeah, this is intended behaviour.

2000 hours of CK2 and I am still didn't learn or see everything. But where is this rule documented?
The
Wiki say this:
With gavelkind succession, dead characters do not "placehold" as they do under
primogeniture. If your firstborn dies, you can expect your second son to inherit rather than an unready grandson.
And the Ingame tooltip say this:
OK, the grandson is listed in the title 'Title loss on succession' notification, in the tooltip in the CoA and in the inheritance tab, but he and other grandsons, of older dead sons, are listed before other direct sons. See here:
1337 Bookmark High Chief Ivan of Vladimir, vassal of golden Horde. He has three living sons, Simeon, Ivan Jr. and Andrei and the oldest one has a son of his own, Vasiliy. Vasiliy is correctly show as the second heir because when Ivan dies and after that Simoen dies he will inherent. But when I kill Simeon before Ivan dies, Vasiliy become the third place on succession but is still show as the second one. This is definitely bugged.
I gave Simeon another son but this one will not inherent anything? Why is this? Is this rule also in place on elective gavel kind?
Gavelkind and elective Gavelkind may be mechanically correct but it is a pain in the ass to correctly foresee the succession when a bunch of kids and grandkids are present. The same goes for the magically title creation in elective Gavelkind. You never know who gets what newly created titles. And I understand that the capital goes to a second in line heir if he isn't able to get any land but it is stupid that you, as a player get no notification for this. Me as a experienced player know how to deal with GK and eGK to not get in a bad situation but it took so many times to understand the inner workings of the laws and as you see I still not know every detail. This needs to be changed! I would like to start a discussion thread about the topic on how the game could present the succession on GK in a more understandable way, but only when you, the devs, are willingly to change something to the better. When you don't care then I choose to don't care either.
