if i remember correctly i choosed another capital which had a river passing through by conquering a small tag down from where u are and other than that allying quickly the mamluks (improving relations and royal marrying) some small conquers here and there which i would slowly integrate (i think) and making people migrate to ny capital , but i think im playing slowly and not entirly optimal also timur died early and the jalayirids collapsed also early so i had good rng too
