[0.15.37] Manually downgraded savefile is corrupted

[somekittens]

Followed rseding's advice here after downgrading to 0.15.37: https://www.reddit.com/r/factorio/comme ... 8/dqdw5cz/

I was able to edit the bytes in level.dat and script.dat, save, and view the save file in Factorio. The Base Mod was highlighted as the wrong version (still showed 0.15.38). When I load the save file, Factorio crashes

Do you happen to have a copy of the save before you edited it? I tried to put it back to 0.15.38 and it still crashes, maybe you edited a value wrong or somthing.

Yup, here's the original. Hex files were edited in Sublime Text 2, if that helps. All I manually changed was the fifth byte (possible that some "helpful" feature changed other things)

I was able to edit/load the original files in 0.15.37 just fine. Seems that the ones you uploaded are truncated - they are identical to my changed versions, up until the end, when they abruptly end, cutting off the end of the file. Approx 1KB of script.dat and approx 32KB of level.dat is missing.

Yeah, you are right, thanks for mentioning that.

Here is the working 0.15.37 save

Good to know, thanks. That's what I get for hex editing via WinRAR.

Thanks so much! We've put a bunch of time into this. Hard to understate my appreciation for your recovery!
