hi first i have to say i love this mod. but resantly i have a problem i have a relly old save game from the time were thermal jet nosals can use Liquid flue so all my supply and crafts are set up. Because the new nosel cant use LF i coppyt a old save of this engin in but by exigently i deleted that. so is it possibl to reintroduce this fule tipe so that my 1000 h save file is not totaly broken . Sorry for spelling and grama and errors
