Lost Blueprints need help

[Nobsniper]

ive been working on a decently sized ship for a while and recently when i tried to save it it got overridden and deleted. what i did was save the ship, then loaded it in to check if it was the right save and so far it was fine but then i closed the game and when i reopended it to work the next day the file had V.0 instead of V.19,20,21 etc. and is unable to be loaded in. i was somewhat fine with losing it for a had the main hull savd in a another folder that seamed to be fine so i strated working on that one bu tthe same thing has happened and ive completely lost the 40k volume ship. when i try using default blueprint to load it into creative it gives the error

Error readsObject reference not set to and instance of an object at Assets.script.persistance.blueprintfile.load

There might still be a .blueprint_backup file in your constructables folder. Saving that as .blueprint should allow you to acces it (it's one version older than the .blueprint was though, afaIk).

how would i know which file is the ship im working on, all the blueprint files i oculd find where either built in or only had a number assigned to differentiat them and i cant tell which was the ship i lost.

It should be "YourShip'sName.blueprint_backup". You shouldn't have found the built-in stuff, if you searched in the correct folder though: C:\Users\YourUsername\Documents\From The Depths\Player Profiles\YourProfilename\Constructables

so when i checked the folder the ship still had both verasions, i.e backkup and blueprint were both there and seemed fine.
