I know this type of problem does occur every once in a while, but I've never been able to fix it, so I'm coming here for help. If there is a simple fix in a post (that I couldn't find), please do not hesitate to notify me of it. I built a craft with KW Rocketry and Nova Punch mods, then after a re-start, I am now getting an error loading the craft. the error says "Craft Loading Error: Craft was not loaded because it is missing the following parts: 1200 fuel tank 1.25 cl.large.shortMonoTank. The problem, is that I had not altered or changed any of the mods before this error. And If I am not mistaken, the 1200 fuel tank is a stock tank. I did a wipe of KSP and resinstalled and put back in exact same mods that I had in before, newly downloaded to ensure they are the most current version, but I'm still getting that error when I attempt to load that specific craft. If any crafts have that specific tank in it, then I can't load it. Am I correct in believing that the 1200 Fuel Tank 1.25 is a stock tank? If not, doesn't' it come in either KW Rocketry or NovaPunch? those are the only two parts mods I use. I also use Kerbal Alarm clock and the Enhanced Visual pack. Any help would be appreciated. Thanks
