I cant send you the save game, beacuse its not able to save.
I send you teh previous savegame like 2 hours older. The autosave is not working of course
why do you want a zipeed savefile? its compressed anyway....ggg

25-07-18_15-51-autosave.save

Now i have stopped and exited to the main menu - knowing that I will lsoe the game. The game crashed on exiting to the mainmenu probably as a result of the "not able to save"-bug

The problem isn't with the game, but with your PC.

This is hard to say. Maybe there is some super rare case where this occurs, or maybe some RAM issue. I don't know how frequently you are hitting this. Obviously, I can load your file and save it fine, but that doesn't say much. But we don't have more of these reports so far, e.g., if you are hitting it frequently, it might be on your side. If not, there is something rare going on.

Thx for your reply.
Actually it was a rare issue: I have an intel 14900k-cpu which was affected by the intel-overvoltage-issue.
The Problems spread, Capitain of industrie was just the first to detect it…ggg
I now have a new CPU, intel replaced it, and am back to work…just a lot to reinstall.
