I play with CK2 v 2.4.5 and SVN 697
I have started a game with a Tsaesci matriach. She ruled for 200 years without problems, except for some occasional CTD.
She died when trying to become immortal, and that's when the game bugged : Her daughter (2nd child, but the first was a male) became the new ruler, but the succession laws became AGNATIC-COGNATIC primogeniture and her heir was now her first grandson. I changed that by restoring enatic with console command allow_laws. But it's strange that the succession removed the "no gender laws" for Tsaesci.
