Successor changing during play

[MichOrion]

During play my successor will change to my nephew (deceased brother's son) from my own son. I have Agnatic Gavelkind succession law. I can remedy this switch by saving and reloading, when I reload my son is successor again.

Old king died and son did inherit now succession switched between the nephew and the his son.

I would say that this sounds quite much like another already reported issue so it's in our internal forums. I guess it happens when you conquer or get a hold of a new holding, for example?

That's correct I've recently conquered another duchy. Thanks.

Same thing happened to me. I conquered two provinces, created new vassals for minor holdings. Next day, my son and heir was excluded from the line of succession; my daughter became heir. Saving and reloading fixed it.
