[16.36] Corrupt Blueprint.dat

[Nightwolf181]

So there i was playing mutliplayer when my house power dies. No biggie reboot the pc hop back on, and now it crashes when i attempt to join a game. Ok not my first rodeo so i go through all the standard steam steps to fix what might be wrong. Whole lotta notta. So after a little bit of digging i find where my blueprints are stored copied the file, and wiped the game and all related files. Clean install, works like a charm. Now i go stick my blueprint.dat back in reboot the game, and crashes on world start every time like a charm, pull out the blueprint.dat, restart a game, saved or new, works like a charm. Stick in my old blueprints, crashes every time. So after more digging im not finding any topics really dealing with what i presume is a corrupt blueprint.dat, maybe im using the wrong phrasing? Is there anyway to fix this? any mod to import blueprints from a folder location, i dont have a string number to copy alas and i have a pretty deep book of bp's i would rather not lose. i included my blueprint.dat and the the autosave as there was no manual save when this occured if anyone has any suggestions.

Looking at the file with a hex editor it seems that it's 60% zeros. Which means your power outage probably happend right in the middle of the game trying to update the file. If that file reproducible makes the game crash that should be fixed though (-> file a bug report or have a mod move this topic). And maybe a nice dev could try to rescue what's left of the first 40% of the file.

Btw, blueprints are also stored in savegames. So as long as you still have a savegame containing the book (chest, inventory) you can just export it back to a fresh library.
