During autosave, the game says I don't have enough disk space and then the game freezes on the loading screen. I have about 500Gb of free space, so that's not the problem. I also tried to delete previous save files, but I get the error anyway. I'm on an iMac with OSX Yosemite.
Thank you.

Try this - Go to Applications -> Utilities -> Disk Utility -> Repair Disk Permissions

Same here, any solutions?

Repair disk permissions doesn't help.

I am experiencing the same problem.

Sometimes it can be temporarily resolved by deleting some older saved games. However, the error can occur also with only 3 saved games.

It happens very randomly and I can't figure out what triggers this. Sometimes I can play for hours having many saved games without getting this error.

I have disabled the Auto Save option to partially mitigate this problem. However you can still get stuck having only 2 or 3 saved games.

I wonder if this is Wine problem.

OS X Yosemite 10.10.5 with plenty of disk space.

same. installed version 2.2.0.7

I'm having this, too... any updates?

The post is FIVE years old.

So? I'm having this problem now, not five years ago... this thread has no answer... what's your point? Why shouldn't I even ask, if anyone solved it?

*Shakes head in disbelief*

I had this too, but it did not reappear after I had reduced the saved games to only what fits on the screen.

I experienced that sometimes some of the deleted saved games reappeared after relaunch.

Do you use cloud sync? It's just a guess. I always wait until the syncronization is completed before and after playing.
