First off, let me start by saying that this is an exceptionally well done mod indeed. However, I have a question regarding the Bulgarian unit roster: Armenian Nobles, Sardar, Uar/Avar Heavy Cavalry and Chionitai Heavy Cavalry are available for Bulgarian custom battles, but during my campaign, I have not been able to recruit them in any of my settlements. I read that some other poster had an issue with Bulgar Lancers as well, which can be solved by changing the export_descr_buildings file in the data directory. What are the requirements for being able to train these units in my settlements as the Bulgars?
