Authetius

First I'd like to say that I've been playing with this mod for about six months now and have loved every moment of it. Thanks for the larger variety of parts. Maybe I just didn't read far enough back, or maybe my skimming and searching simply missed, but since the last ksp update the engine shrouds have disappeared making for some awkward looking stacks. Is there a fix for this I simply missed, or were they removed for a reason?
