I"m going to suggest that there be a way (other than waiting for them to time out) of getting rid of the locked boxes and tool kits. Right now I have 11 locked boxes (8 gold and 3 silver that won't merge), as well as almost a dozen tool kits of various levels (that also won't merge), pairs of everything else, no empty spaces available. I don't have enough $ to buy new land, and can't get any more $ because I don't have any spaces for the $ to go. It's very frustrating to have to wait a week to free up spaces, especially when I know that I'll just get more locked boxes/tool kits in the future. Other than that, I really love this game.
