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 ...

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 ...
