That looks like I may have missed part of the vessel when making the silhouettes.
Names.cfg says "KSCSTaihosan=Composite Superstructure Freighter"
KSCSTaihosan.cfg says it is using the NKSCSTaihosan model.
My NKCSCTaihosan.dat looks like the silhouette that NavelIntel reported instead of the vessel he was actually seeing.
When comparing the "real" Taihosan" there is a stack and some cables that is not on my silhouette. I suspect I had just missed it when exporting the objects from the model file. I will correct it asap.
