I keep getting random crashing while playing as an Arab nation. It starts happening around 20 years into the game, and there isn't an obvious cause for them.

This is my error log

Thanks. It might have to do with the form Arabia decision. I'll take a look at it for the next update.

Also yeah, that decision doesnt work either. They may be connected.

Sassanid persia is ruled by a frankish chalcedonian shahanshah

all of the royal houses are bugged and rule the wrong countries actually

For the wrong rulers issue, delete your paradox folder in documents. Make sure to backup your saves before you do this. Should fix the issue.

For all, Infinite loading screens problems, make sure you use the right version of the game for the version of the mod.

If the characters are getting switch up try and delete every thing in C:\Users\You\Documents\Paradox Interactive\Imperator
Expect the saves, and mods of course.
