I've tested and re-tested this and i'm not sure what's happening.
I have a sorceress. She's nude. I sculpt a wrap around her breasts. It looks good. I save and make a backup save. I quit Blender.
When I come back, all my sculpted information has vanished, like it never happened, even on the backup.
I've tried exiting sculpt mode and saving in object mode as well. Everything looks fine and then I exit the program and all my sculpted information is gone. What's more confusing is, all my sculpted information up to this point is still there. Just this one area...
I can't find any information online about this happening. I'm not sure what's going on. Any help on this would be very much appreciated!
