Was working on a ship and added an extra i.e. decorative component. Didn't like it, so I click on the component on the ship model and tried to remove it. Was told I couldn't because it had other parts attached. Thought, that's odd, I just added it and haven't done anything else. So I clicked its icon in the components scroller thingie and tried to remove it -- same thing! I am 100% positive that this is not user error and that I added a component that somehow linked itself to an existing part of the ship. Stardock, for the love of all that is holy, PLEASE allow us to override the "this component has other parts attached to it" warning, even if it means we lose many components at once or possibly corrupt the .shipclass file!
