deposits disappear

Hi. There has been an issue that keeps bothering me. When I find a new deposit, say iron, and start building mine, every time I stop the construction in the building queue the deposit will also disappear with the mine. This is especially annoying with deposit that require some amount of time to find like coal. I think this should be fixed right away

Don't stop the construction then. This is a lot more advantageous than disadvantageous. When searching for fast mines, it allows you to get rid of the normal mines and try again.
