Alot of nobles look the same, especially the ALL of the nobles of (excluding defectors): Turguhn Horde, Mithridian Empire, and the Acztoac Empire. They all look similar but only with an age difference and whiter hair.

Another issue I found was that some nobles (this is an example) have fathers, and sometimes it is really broken. Some lords are 3 with fathers who are 26 and I dont understand, and immediently I turned Dynamic Years off, so, whats the problem?
