Summary​

Dissolution faction disabled by the Iranian Intermezzo 200 years after it ended

Description​

During my 2 latest games I have tried the "Lesser" realm stability game rule and, while massive civil wars occured in most realms, the Abbasids were weirdly stable. After gaining a border with them to become their vassals, I realized that the Dissolution faction was disabled because of an ongoing struggle despite the fact that the Iranian Intermezzo had reached a Concession ending somewhere during the tenth century in both cases.
The game rule is the only cause that I can think of because it's the only difference with 2 other games started in 867 where I was able to dissolve the empire or I witnessed it happening (all the saves mentionned were made after Khan of the Steppes came out)

Steps to reproduce​

Enable the "Lesser" realm stability game rule while starting in 867
Play until the end of the Iranian Intermezzo
Try to create a dissolution faction
