We do have a back up saves option in ArtRage 4, which will keep extra save files with previous version. You still have to remember to actually save, though.
Autosave would be one thing.
But I have learnt to 'save AS' regularly, because if Artrage crashes it brings back the bottom layer only. (And I work on many layers.)
Saving is always a good idea, no matter how good the program, in case of sudden lightning strikes and cats on the keyboard. ArtRage will try and save everything it can when it crashes or is suddenly shut down for any reason, which may mean just the bottom layer, or it may be more than that. It may also just be the top half of the image, or similar. How much it saves depends on how and why the program shut down, and how quickly this happened.
This applies for general computer crashes as well, but if it's just ArtRage, and if ArtRage is crashing on you a lot, there may be a reason for this, which we can look into if you contact

If you get a damaged save that still appears as an image thumbnail (you can see the preview in your folder), then you can use File > Import... to open the file, and import the PNG preview of the painting. This will be on a single layer, and only have whatever was visible at the time (no hidden layers), but it will be full size and decent quality.
