Welp, crashed to desktop and lost about a week of gameplay.

It happened when I was burning rotten meat, sinew and bones on a brazier. The brazier was surrounded by items on all sides because I had dropped tons of the stuff. My plan was to burn it all away. I burnt a few items, and then picked up the next load. As I was dropping them into the brazier, the game crashed.
The only reason I didn't have Autosave on is because it saves too frequently... and I then I kinda forgot about it, because the game used to do it unobtrusively and I forgot. :c And because it had never crashed yet up to that point.
Edit: I turned Autosave on now and it's causing some pretty hilarious bugs during crafting. I started crafting some Batteries and it decided that was the perfect time to save. Now it thinks I have every possible permutation of every item available to use. I'm going to tell it to use Lemons which don't exist within a 100 mile radius of me, what's the worst that could happen?
