Extremely unstable later in the game

I can never get to a point where I can complete the game. After around 200 turns the game becomes very unstable and crashes about every 2 or 3 turns. It’s very frustrating. I’ve played it on two different iMac computers and it’s the same on both. This version is the worst they’ve released. Do not buy it/upgrade until they release some stability fixes.
