I keep getting this message after the game idles for a while "NaN value loaded from input file. File could be corrupted."

Hello! Thanks for your report! It's is an odd error. It could be that the files became corrupted somehow, which would not be a mod problem but a computer problem. Could you send me the log file next time this happens?

For a more immediate fix, you could try deleting Hall of Fame and downloading it again. You can also check the integrety of your Factorio game files in steam.

I have also received this exact message for the first time today though I haven't been playing so often. I messaged you the file on discord because I wasn't sure how to message you it here?

Thanks! I just reproduced it, and tracked it down to the 2014 Trailer map breaking. If I recal correctly this is a new feature of that came out in the last few versions where the games does more validity checks on saves on startup. So I will have to figure out why that specific save is corrupted :)

Fixed in 1.13.1 :)
