[2.0.15] Build 80108 - Corrupt Map. Unknown Decorative ID

[Mobasity]

In some incredibly fortunate turn of events, it seems that while working on my last project on this save, I accidentally clicked on 'Launch to Aquilo', which saved triggered an autosave about 3 hours before the corruption hit.

After updating to Experimental 2.0.18 the game displayed 'Corrupt Map Unknown decorative prototye ID 42240', which gave me gave me a few resources I could look at, which points to this possibly being a memory issue? Im going to run some mem tests tomorrow morning to see if thats the case.

So while I no longer need this fixed, if this is a bug that may impact others ill leave this post here.

Notice - Corrupt map. Unknown decorative ID: 42240.

Ive looked high and low through google and these forums before making this post, I cant seem to even find a mention of ' Corrupt Map Unknown Decorative ID', which feels quite worrying. All saves relating to this world have been corrupt (main save, temp save, last 3 auto saves), and I have absolutely no idea what caused this. I queued up some science, saved my game and then went AFK, came back to a crashed game and my saves would not open upon relaunching the game.

I have tried loading all auto saves, and the save I made right before leaving my computer, with no luck. Ive validated game files and checked for updates and no luck.

I have tried updating to the experimental build [2.0.18], and opening the saves, and I get the almost the same results, but the error now says 'Corrupt Map Unknown decorative prototype ID 42240'


The follow are the saves from most recent to least recent.

1) _autosave1
2) _autosave2
3) _autosave3
4) Pre-AFK



I have no idea if there is anything anyone can do about this, but if any more information is needed please let me know, id hate to lose 365 hours of progress.

Google Drive with all 4 saves included, as well as factorio-current and factorio.previous logs as well as the dmp file.

I just ran into the same issue trying to load up my save today. The error says "Corrupt map: unknown decorative prototype ID 1170." on the latest experimental version (2.0.19) and "Corrupt map. Unknown decorative ID: 1170." on the latest stable version (2.0.15).

The 3 previous autosaves are also corrupted, although the oldest 2 give ID: 1084 as the problem.

The only other save is from 40 hours ago, which might just be the end of my time with Space Age for a little while if I have to go back to that.

Here's a link to all the relevant files.

Really hoping to get a solution to this...

Thanks, ~Green

I also have the same problem, on the exact same game version (but on Linux). "Corrupt map. Unknown decorative ID: 16466" when I try and load my save, and the autosaves all say the same thing. I had some sort of disk error that didn't cause any problems using my computer until the next day when I tried to load the saves up, so that's probably what caused it (and I have now fixed)
Older saves load fine, but they are quite a while back from this one.

I'm hoping it's something simple with just a single data value somewhere. I tried to load the save files in a hex editor, but this is so far above my head.
Thank you to whoever has a look!
