I was trying to copy a blueprint book from my blueprint library ("My Blueprints" tab) to my inventory. I accidentally hit shift-click, and it moved all my books from my library to my inventory, leaving my library nearly empty! (There were some left because my inventory was full). Honestly, I feel this is a bug, as doing this appeared to have cleared out my saved blueprints that I use in all my games, which is very bad
But when I tried to copy the books back into my library, one by one, by control-clicking them, I got a couple done, then Factorio crashed. See the attached crash log and dump.
Luckily, when I restarted Factorio and opened a different save (a new one created in 1.0 directly) the blueprint library seems intact, so at least all my blueprints didn't get lost...
