1. I was tabbed out of Factorio working on something else while connected to a modded game hosted by another player. 2. I had been connected to the game for several hours when suddenly the game popped up an new window stating the game had crashed. 3. I expected Factorio to not unexpectedly crash 4. ...

I love the idea of a blueprint mode, It would be quite fun to design a modular factory that you can quickly place down.

I see, hopefully this gets patched soon.

Neither my friend nor I was driving a train at the time of the crash.

I'm not 100% sure what happened but I will explain as best as I can. I was playing factorio in windowed mode, and i moved my cursor to chrome in my second monitor. Then when i clicked back into the game, it crashed. Log file: https://pastebin.com/csQRjwhr World: https://www.dropbox.com/s/c0oavmnren2...
