Corrupt map: Unknown item prototype ID 20384 (saved game uploaded) (Will pay $50AUD for a fix for this)

Post by andyseemight »

Hello everyone.

I was playing my 486 hour long map, midway through designing a new ship when suddenly it just crashes to the menu with the error in the title. The full message was "Corrupt map: Unknown item prototype ID 20384. File has likely been corrupted due to failing hardware". I thoroughly tested my hardware to the point of madness and it is absolutely perfectly fine. Ram is only a few months old and is perfectly healthy each individual stick tested separately.

Here are my current error logs right after this happened.

If Prototype ID 20384 is in reference to an item in the game can I just go into the file and delete it some how? the file is 277mb so it's not really easy to upload anywhere... EDIT: Just found out how to upload it somewhere!

I have tried with no mods loaded and with all the mods in the error logs loaded and still the same error. Also all my auto-saves from this same saved game are suddenly corrupted all at the same time despite working just a few hours before.

Has anyone got any ideas? Does anyone know of any tools where I can do investigation of my own into the save game files?

I looked at this save file but i am unable to identify where is it corrupted.

Just curious what in the save file are you looking at? is it the level.dat files through a hex editor?

Also not sure if this helps but I installed the visible planets mod at around the same time the saves became corrupted. It could have been a coincidence though.

Haven't seen anyone else with the same problem so maybe it's not related.

Mods are not likely to cause that type of corruption, there are some restrictions what mods can do and they definitely cannot touch raw data stream while it is being saved or loaded. In this case there was some corruption with EjectedItems on one of the space platforms, i am not sure but having about 5000000 ejected items on one platform is really suspicious, they should expire within 5 seconds so maybe the amount of ejected items to load is corrupted. Anyway, if you have no reproduction steps how to cause such corruption from a known good save file there is not much i am willing to do, if it was caused by failing hardware there is a chance it may become corrupted again and i do not want to be fixing save files over and over again. I am fixing them more like an exception to maybe find some clues for underlying issue but i never found any so i am just not fixing saves anymore if its more than 1 byte corrupted in an obvious place.

Thank you again for looking into this. Judging from what you said here regarding platforms is it possible to delete entirely the suspect platform? or every platform if that is easier?

On your place i would really focus on making sure that the machine you are using is not faulty, verify if memory has no bad cells, maybe run some cpu diagnostics. If this save file was corrupted, there is a high chance that in the future you will get more save files corrupted and i wont be fixing any more save files for you.

I was looking more into this save file and this is what i found: game tick at the time of this save file is 104985046. One of the space platforms's second oldest ejected item was created at game tick 103265869. That is almost 8 hours of time the game remained corrupted. Oldest item has a corrupted tick of expiration which caused game logic to fail to clear ejected items because they are supposed to be stored with increasing tick of expiration and the first record in the queue was showing a tick that was still in the future causing game to think it still needs to wait until removing any items. Because of that, items were not removed. This caused about 5028125 items to accumulate inside of the ejected items of that space platform. That is roughly 231MB of data in your 740MB large save file (when counting uncompressed). In addition to the first ejected item being corrupted causing ejected items to not flush properly, there were at least 2 other ejected items that were corrupted on the ItemID field where they say what item they represent. With hex editor i cannot do too many intrusive changes because a lot of saving systems depends on exact sequence of operations while loading, it is already pain in the butt to remove objects using hex editor if those objects contain MapPositions because they are using delta saving so by removing one block of data i could cause all subsequent map positions to load incorrectly. I decided to locate where those ejected items start in the save file and where they end and decided to just delete about 5027764 ejected items, leaving only 361 of the newest ones (first one i kept had MapPosition saved without using deltas, meaning it should not corrupt any subsequent map positions loaded).

Here is what i got after this surgery: https://drive.google.com/file/d/1o1N2BV ... sp=sharing - this save file takes only 154MB (compared to 282MB of the original). I only verified that it loads and passes consistency check, i cannot guarantee that there are no other faults in it.

As for the money promise from your changed topic title, put it into your moneybox for a new hardware if the current hardware would need some replacements.

I ran memtest86+ all night again (ran it after the initial corruption to verify) and it revealed nothing wrong on any passes again. The CPU I just stressed tested it and monitored temperatures for an hour, do you have any recommendations for a good CPU diagnostic tool for linux? because I know a temperature check isn't sufficient for verifying hardware issues.

If this helps at all I do remember the UPS tanking over 2 hours to almost unplayable rates which should have been a sign but I was building things so I thought that was due to that.

I am so grateful you did this! as for the $50 I'll buy factorio and gift it to so some one as it should benefit us all. Another player another factory to grow!

I work week on and week off and I was itching to get back to growing the factory since my first day off only for this to happen on my first day off lol. So thank you again for salvaging this so my week off can be put to what god intended... growing factories!

Thanks again and I understand you can only do this a limited amount of times. I have backed this up and going to create a script in linux to create different folders of saves and date them every few hours!

Use Prime95.

Put it into Syncthing, it will do it for you automatically, keeping a separate version of every changed file in regular intervals or keeping defined number of versions.

Hey just an update to this.

My motherboard is a X670E Steel Legend and I'm using 64gb of Ram. There was a period where Factorio was using almost 40gb+ and I'd get the occasional crash every few hours. My ram sticks were actually in their slots perfectly fine (or so I thought) and had clicked in which made me believe they were in correctly. Even though they had "clicked" in they could still go down a tiny bit further, probably a quarter of a millimetre more. Ever since I was able to push them down that extra space I've never had a single crash in more than 200 hours of playing when before I'd get a crash every 4-8 hours!

I don't ever remember having that extra space to push a ram stick in further once a click is heard with DDR4 but it seems with this motherboard which is DDR5 there is that extra space and that is what was causing my instability and corrupt saved games.
