Crashing on loading all recent saves - latest build Steam

[oodle600]

Hi all,

I appreciate you taking the time to look into this.

I was playing Factorio a few hours ago without any issue, upon trying to load my main game save now, the game crashes.
This is also applicable to all 3 of the autosaves.
I am able to load much older saves, but I would rather not lose 10+ hours of work.

What did you do?
Save the game manually and then close the game from the menu. Upon launching the game, I tried to 'continue' and the game crashed after the loading bar reached 100%.

What happened?
The game froze, then I heard the windows error noise, I Alt+Tabbed to the error and opened the log. I have since tried to reload the other autosaves but experienced the same outcome.

What did you expect to happen instead? It might be obvious to you, but do it anyway
I expected the game to load without any errors.

Am I correct to say this is the error?

Code: Select all

Stack trace logging done
  24.549 Error FourDirectionPointers.hpp:24: Wrong direction of FourDirectionPointers.

Any fix is appreciated, I don't mind getting technical

EDIT: This is with 0 mods installed but occurred after I used a cheat command to set the biters to peaceful

This is not the game issue but rather a corrupted save file. The crash itself is quite obvious since it is trying to setup express-transport-belt at position {371.5, -128.5} which has direction of... NorthEast

Here is a fixed save file. I managed to fix it with hex editor by changing exactly 1 byte from a value of 0x11 into 0x00 (after repackaging the chunked level.dat into a one larger piece with some internal tools):

Do you have any clues about what was happening here?

I have no clue, I have not even touched that area for well over 20 hours of game time.
Is there any other way I can help work out what would have caused this?

That transport belt is part of a system to get both transporter lanes full, just a laziness

EDIT!!!: I became so distracted trying to work out what happened I completely forgot to say THANK YOU!!!
