Please explain your issue is in as much detail as possible.
As the Byzantine Empire, losing an imperial election is set to cause me to lose all my titles. All titles besides the Byzantine Empire are shown as Agnatic-Cognatic Primogeniture, but even though I have a son he is not set to inherit those titles. If I land my son, I am still projected to lose all of my titles and the game. I've had this issue in other Byzantine Empire playthroughs, but the issue does not occur for every imperial election. The current character's father was also emperor but even though I had lost the imperial election on that character's death I kept all of my titles except for the emperorship.

Steps to reproduce the issue.
Play as the Byzantine Emperor and be projected to lose an imperial election. Bug does not occur for every imperial election, unsure what causes some elections to function correctly and others to have this issue.

I can confirm that this occurs, I've seen it in my recent Byzantine game as well and wondered why this was projected to happen.

I have had warnings for this. Despite having grown up son and several young daughters, the youngest with "Born in Purple" but first when I recieved a "Born in Purple" son, the warning dissapeared. Before that, the commander listed to be next emperer was set to inherit every title I had. Now the newborn was listed for all counties. My elder son had nothing, but was listed to be 2nd in line for the counties.
