"Break"
I have an idea to where they add a thing for builders called "break"where your builders are all occupied,you can press "break"and it goes and upgrades/finishes what ever else you want to get rid of, but for a price. It can either cost gold or elixir 100000 in mind, or you can go on break and upgrade or remove whatever obstacle or anything but it wont go straight back to work, it needs time to regenerate and the builder leaves the thing being upgraded alone for a certain amount of time. Idk it just came to mind, thanks!
