Factorio crashes when loading a new game in vanilla

[Fireball770]

I noticed I could not load my space exploration map. I removed all mods. I tried to create a new map but when it was created and I loaded in to the rocket, it crashed. I expect the game to operate as intended. It always happens, I tried a few times including restarting my computer.

I forgot to mention I am on steam and have already verified steam files.

I figured it out. I must have had a bad blueprint so removing blueprintstorage.dat and getting blueprints from a slightly old save worked

IMO, the game should not crash with a bad blueprintstorage.dat. It should rather ignore or sanitize the problem.
Not sure, maybe devs would like to have a look at the file and check what happens with it?

The blueprint.dat file is not supposed to be corrupt in this way. This kind of corruption indicates something or someone tampered with the creation of the blueprint and left it in an inconsistent and broken state that the game isn't setup to handle.

There's likely a bug with how ever it got into this state that we need to patch. But first we need to know how it got into that broken state from a working state.

Fair, it's probably something, where you cant handle every case afterwards

Another idea could be to make regular backups of that file. It's currently quite fragile compared to regular savefiles.
