First of all, thanks for all the mods you've made Nathan Secondly, I haven't read the entire thread in exact detail so I don't know if its been said yet, but when copying a Stretchy tank that isn't of default length (1.875m), the attachment nodes of the copy are at the default position and not changeable anymore (either inside, or outside the tank). It also kinda breaks symmetry sometimes when trying to make multi body rockets with the stock adapter parts. Another thing i wanted to ask, now that we can adjust the diameter of the tanks, why do the tanks with different unadjustable diameters still exist?
