Sorry, no Phi/Ind in the pack, not due to balancing issues (Mansa is Sci/Fin after all). It is because none of the LHs I added seem to call for that. IMO Lenin should be Phi/Ind, but he was added by Zappara and carried over by Afforess. I think the biggest trait issue is that Protective, Aggressive, Charismatic, Imperialist, and Expansive are overused, but that has to do with what LHs I could dig up for some of the more "minor" civs due to the fact that many noteworthy leaders were warmongers or defending against warmongers. WoC_installer.jar is designed to add the extra audio content, so it is worth running just for the LH Pack (Putin, Hitler, Akbar, Meiji, and several others have diplomacy music). Roughly 50% of civs have added audio content, mainly diplomacy music, which should answer your second question. There should be no errors since I have removed civs for testing due to loading time, so it should be fine. I have had errors with it due to my own impatience with it working, but that is a different issue. Have you tried running Civ in English? That might be part of the problem in addition to memory issues which have been stated. I doubt that it will work, mainly due to starting techs and Better RoM changes. I think strategyonly plans on adding Civs his style to Pre-NWA. Two LHs should be Hum/Org: Urukagina of Sumeria and Pastrana Colombia. With 200+ LHs, it is easy to miss. Personally, I like the -70% upkeep aspect, since Humanitarian also makes Expansive and Charismatic seem powerful as well (I forgot if I added Hum/Exp, but I doubt it). Balancing-wise, I think it is fair since Mansa is Sci/Fin, which is incredibly powerful for Research.
