How much "pain" is this causing you?
6

Please explain the issue you experienced in the most condensed way possible
The Sassanid dynasty tree and its characters (maybe others too) cannot be viewed

Please explain how to reproduce the issue
I can start the game as any character in the earliest start date and try to open the dynasty tree of the Sassanid dynasty, but it will not work.

If I select house Bavandid and try to view the Sassanid dynasty tree, it will only show house Bavandid - as house Bavandid is a cadet branch. There is no "+"which I can use to view the dead dynasty tree or any characters or other cadet branches of the Sassanids.

If I select and play as another character outside of house Bavandid, trying to view the dynasty tree of the Sassanid dynasty will sometimes also show a blank dynasty tree for "lowborn", so actually shows nothing at all.

However I test this, I am unable to view the Sassanid dynasty tree.

Is there anything else you think could help us identify/replicate the issue?
No

I have attached a save game
No

So, no answer to this? I have another problem with the dynasty tree: I can only see the ancestors form the mothers side. The titles are coming obviously from the fathers side. Is there a button I have yet to find to switch between both sides? Or ist it actually broken?
