I've already posted this on your GitHub, but I'm mentioning this here just in case you check it more frequently. KRnD uses the old pre-1.5 masses for Making History Engine plates (.075t) instead of the new (~.013-.007t) resulting in negative mass for some or all variants upon upgrading, leaving the part completely broken and unlaunchable. Probably just need to update the default mass or add them to the blacklist if you can't.
