Level.dat currupted?

[Ash6390]

A couple of days ago I was playing Factorio normally and having a lot of fun. When done I saved the world, back to the main menu and clicked the Quit button. My computer crashed, I had to go out anyway so I just went out and thought: let's hope nothing too drastic happened. When I came back to my computer and tried booting up my world it didn't show up in the list, so I went in my Factorio folder and found the zip was corrupted. I tried fixing it, eventually it opened up, but now I found that my level.dat is corrupt, when I try to unzip it 7-Zip tells me: "CRC not correct" or something like that. I attached the ZIP so that you guys can check. I had over 31 hours of play time on that world and would be really sad if it's gone.

Sincerely, Ash

Oh yes, when I try to open the world in factorio it throws this log:

crashing computers can do stuff like that at least you can still use autosaves

I had autosaves disabled because I was playing with a friend of mine and it crashed every time it saved

Where's your bug report about that?

I actually didn't make one, thanks for the reminder. I'll work on it.

EDIT: I lied, I turned it off because it was kicking my friend every time it saved, it didn't crash .

[kinnom]

still a bug

[Ash6390]

still a bug

Mmh, I'll test if it still happens and if it does I'll make a bug report about it.

EDIT: Yep, it doesn't happen anymore, I'm dumb. But we are going in another direction here, what about my world, has anyone tried fixing it?

[prg]

Ah, the latest edit to your first post now shows a crash when loading the save. That's a bug and should be reported. The game must not crash no matter how badly corrupted the file is. And who knows, maybe after that crash is fixed (part of) the map might become usable again. Anyway your best bet for having someone fix the save is to ask the devs since they're the only ones who know anything about the level.dat format.

Oh ok, thanks for clearing this up a little, I'll report it.

Oh yes, where can I go to contact the devs, IF I can? EDIT:Found it.

about half of level.dat is missing from the save file. it's gone.
