The script ask for non-custom textures, while sometimes overlook the REAL custom skins; and sometimes it even ask twice for the same textures. There are others bugs, but nothing major.
The older models don't have useless textures as far as I remember. Regardless, Darky will have to fix it sooner or later; and since every x months a new bug pop out, the more time it pass, the more work he'll have to do...
