1.8.8.5 just wiped out my save games;when I try to load i get a message about my save game no longer matching the load.This happen to anybody else? What the hellis going on?

In the main menu bring down the console and type developer 1. Then load your saved game. Save it again (replacing the save.) Then bring down the console again and type developer 0.

That save should work. If you have more than one save then repeat loading and saving just remember to turn off developer mode when you are done.

Thanks! It worked1
I got a message saying, though, that acheimvents were disabled. No big thing for me, but annoying.

I still got achievements after doing this. I guess "developer 1" deactivates them but if you set it back to "developer 0" and load the updated game they apparently work again.
