PanzerkampfwagenIV

I know this thread is old but after I recovered my deleted save file from recuva all of my craft files are "unknown size" or NaN Here is the list of my mods: AirplanePlus BDarmory Firespitter Kerbal foundries North Kerbin Dynamics World stabilizer Vessel Mover Starwarsmod And my PC specs: Windows 7 Ultimate Processor: AMD A4-3400 APU with Radeon(tm) HD Graphics 2.70 GHz RAM: 2.00 System type: 32-bit Operating system And btw my ksp version is 1.3.1 I don't think that it was caused by the mods or my PC but after I recovered my deleted save file and my Craft's become "unknown size" but any help will be appreciated

How can I fix this? I know this thread is old but after I recovered my deleted save all of the craft are corrupted or "unkown size" How to fix this?

Same after I restored my deleted save all of my craft is corrupted or said unknown size
