I'm creating this thread so people can document the crashes they are experiencing and together we can hopefully pinpoint what's causing them. Here's what I know:

People are generally experiencing a crash around turn ~150 that recurs when they attempt to reload the game and play through the turn. Going a few turns back in your autosave log sometimes solves the problem, and sometimes does not, which implies that there is a voluntary action taken by the AI that is causing it.

So here's the information I want from you:

1. What turn was your crash?

2. What civ were you? What civs were in the game? What city states were in the game?

3. What mods were you running? Include all DLC

4. Can you avoid your crash by reloading an earlier autosave? Or does it happen inevitably?

5. Using an XML editor, open up your timeline.log and unitoperations.log from the time of the crash and include it in your post. Google how to do this if you don't know.
