I have gotten 2 crashes in the last 2 hours. It seemed very stable up until then. I'm on turn 200. I can restart the game from last save or auto-save no problem & the game goes on past point of crash with no issues.
Windows 10 Home, version 10.0.19042, English
Intel core i7-2600 @3.4 GHz, 4 cores

I do have a debug err file in My Games\GalCiv IV from my last crash. Here's the Dropbox link.
