When opening the Cart Assembler the information pane on the right is empty. When I insert a hull it gives me the information in the screenshot shown below. It seems like that information should be the default text with no hull inserted. This also means that when I have a hull inserted I don't see any information about the capabilites of the hull. The Assemble button also stays grayed out even when I have a valid cart that can be assembled. The button will work when I click on it but it's very confusing. The screenshot also shows this as I made sure I put together a valid cart (There's a creative upgrade attached to the assembler so that's why there is no fuel).
