Hi! I am currently playing a Pontos campaign (very fun!) and I have encountered a persistent CTD after capturing Antiocheia and trying to build triereis with the existent Naval infrastructures there. The CTD occurs the turn the triereis should finish its production. Curiously, that don't happens if I build a lemboy (the small boat that need 2 turns). This CTD has been persistent to me and finally I found I could pass it by stopping the production of the triereis on Antiocheia. I don't know if this may happen to someone else, or with tetrereis or other boats por Pontos.
