We did restart the game, like you suggested, multiple times. Still constantly getting OoS error every 3 turns. However we do have many features on(revolutions, assimilation, random events etc.) and maybe they are the cause? Going to double check BUG settings on both just in case if there is some variable unsynched. Glad to hear if most of the problems are truly solved already. Guess it is just a taste then what you pick up as your settings for the game.
