This can happen when you started the game a very long time ago, or started a game from the map editor after saving it as a scenario.

Unzip the save game, and open the folder:

Then delete everything except for the level.dat and script.dat.
NOTE: The level.dat might be split into numbered chunks, e.g level1.dat, level2.dat, level.datmetadata. Don't delete any of them.

: explorer_2021-01-31_15-00-38.png (1.31 KiB) Viewed 6771 times

Now copy these 2 files into the save game folder:

control.lua: (118 Bytes) Downloaded 214 times

freeplay.lua: (6.18 KiB) Downloaded 213 times

(These files can also be found in Factorio/Base/Scenarios/Freeplay, if you take them from there be sure to COPY not MOVE)

: explorer_2021-01-31_15-01-26.png (5.24 KiB) Viewed 6771 times

And it should load again.

If that doesn't work post your save game here I and will look at it.

This did not work for me, unfortunately. Here is my original save:

_autosave3.zip: (9.45 MiB) Downloaded 149 times

Doesn't work for me either, it can't find the "level.dat", although i have level.dat0 to level.dat32

same level as viewtopic.php?f=7&t=95480

level.datX (where X = "metadata" or numbers) is just a level.dat in disguise. Just keep all of those. This save format was introduced recently in 1.1.14 so it had to already load fine in 1.1.14+ and be saved in that new version, that most likely means you do not need any of those fixing steps as save file was already loading fine in one of those recent version.

I keept them but it didnt work

The problem is, that I cant launch rockets anymore in that save, although i used to be. Is there maybe a command to "finish" the game?
EDIT:
Clarification, I deleted all files as instructed above, exept for all the level.dat files and the scripts, inserted the designated files and it returned the aforementioned error

Your specific case is a bug, which I have now fixed for the next release (1.1.20)

Great work! That's some fast dev work!

Hello. I have same error with my save. Tried both fixes and they didn't work.

Can u possibly fix my save? 58 play hours...

Edit: I was able to somehow recover a save by using map editor and converting a save into a scenario. So i kinda saved factory.
And somehow today my saves just was able to load without errors. Dunno why. But somehow it all works now, i think there was a patch today too.

Posted: **Sat Feb 20, 2021 11:22 pm**

Did not work for me either. The new save does not even display that it is the incorrect version, loading itself is not possible.

Hello! I've been struggling with this for a while now. My save has many level.dat files but no one file named "level.dat" without a number affixed to the end.

: Capture.PNG (3.84 KiB) Viewed 4598 times

I just loaded the backup and it still runs (but will crash if I click on the rocket silo GUI at the top left or if I launch a rocket). After applying the fix I receive an error looking for "level.dat" (I triple-checked that I didn't delete it by mistake, and did not LOL) and it won't load or allow me to convert to a scenario.

I've attached a copy of my save after following the steps above. Would you mind taking a look? (I have many many hours on this one and would hate to lose it).

I have the backup I made as well if you need me to upload that. Any help would be much appreciated! Thank you!

A while ago the devs change how saving works. Newer versions of Factorio saves multiple `level.datX` files, instead of only one `level.dat`, so there's nothing missing

Are you running the newest version of Factorio? I've had it before complain about not finding `level.dat`, but that was because I was trying to load a newer save on an older version of Factorio.

Thanks for de-mystifying my many files LOL! I'm running the current version of Factorio. Just downloaded the latest version this morning.

The one you uploaded has a second nested directory inside the zip - there should only be one. It's still missing files though when that's fixed. Upload your backup copy that still loads.

Attached is the original save file that still runs. Thanks for looking!

Nothing attached there. Make sure you give it time to upload and double check after posting.
