Recovering lost maps after computer crash

[Bag]

Hi - was wondering if anyone knew if there is any way to manually (or otherwise) recover unsaved maps? I was in the middle of editing one when my laptop crashed. Was just wondering if there was anywhere within the game files where this kind of thing is stored in the event of mishaps like this. (incidentally, other apps I had open at the time of the crash managed to recover unsaved data so if BfW has such a feature it should in theory be possible to recover the lost data.)

The editor doesn't create any work-in-progress files. The only surviving copy is the memories in your head, sorry.
