Autosave stopped working

[AndISayMoreAsbestos]

Last night I played TLD for about five consecutive hours. At some point I realized the autosave stopped working, because I was not getting the hatchet notification in the lower right corner. I tried sleeping and going in/out of buildings to get it to work again, but I got nothing. Once I quit, I found out about half of what I played did not save.

Is there a particular reason this happened to me? I was wondering if maybe that happens when you play too long, because I don't remember the last time I played that many hours in a row. Any help/hints for future play, or any troubleshooting would be greatly appreciated!

If you are in WINTERMUTE, there is an timed autosave, in sandbox, there is no autosave, you can only save by entering a building or sleep/passing time for at least an hour. If you did these actions and it did not save, report the bug on the support portal. But most likely, you aren't getting your save back.
