I'm now quite satisfy with all non Eastern kingdom's ethnic. Now problem here is.
1) Do new condition on "coward" trait work? Are they cause CTD in postbattle or enemy turn? If they have problem, please report me along with its symptom and symptom's history?
2) How to Implement Eastern Kingdom? In current condition I just give them marriage/adopt/lesserAdopt only outcast as slave rebel faction but I not yet satisfied. At first I think all there marriage/adopt should be only babylonian and Persian to made them simple but problem is those Berber and Ethiopian which not connected main part of middle east to married with Persian and Babylonian and I also doesn't know specific father in law condition/Stepfather condition to implement their specific marriage conditions. Other way is turn off their marriage/adopt/lesserAdopt option for Eastern Kingdom but increase their fertility rate and allow them to have only male children to keep their pedigree to separated and pure, but could it possible?
Anyone who have knowledge/idea please express your opinion/knowlegde to help me solve these problem.
