k/t I think that the problem is the fact that even i reinstalled BC again, for some reason the regions' names are those that byzantineboy used to his submod. I checked the corresponding files, but the names have the vanilla ones, but ingame they don't! Don't ask me how that happens, but it happens.
As I know these 2 submods are incompatible, so that'w why I have CTDs. My PC wants format in order to delete uterly some files. I'm 100% sure that I didn't do any installation mistake with your submod. I did delete map.rwm which is inside world/maps/base and not inside imperial_campaign as you wrote. No offence! Tha't the only reason I can think it's responsible for the CTD.
Also a member from my HS who had the JKD submod and uninstalled it (I sent him my current vanilla data), installed your submod and he could recruit as the Seljuks of Rum only ships and siege werapons.
