Seems the AI prefers me killing them than letting me negotiate a peace treaty. After taking their main cities and capital they still say "come to beg for mercy" or "Lost the will to fight". Sp can even propose peace is there anyway to remove this none peace period all together, as I find it immersion breaking. Also on a side note I really need to start disabling civs which can just swallow every city state, as I have just liberated a city state only for Mongolia so swallow them up while I was its Ally. Great mod overall though.
