Having selected the clan castle, you see the treasury icon. It is always coloured. Chen you click on the treasury, you see what, if anything, is inside. If something, you can collected it. If nothing, the options are grey.
Please make the treasury icon greyed out so that from the clan castle menu you can see immediately if there is anything in the clan castle, or nothing.
Even better, show a Treasury icon up with the resources display if there is anything in the Treasury.
