You aren't the first person to mention this - but I've played many games on many browsers and have never seen it happen. The only thing I can think of that would cause this is if the storehouse and hut were placed in the same spot, the storehouse would overwrite the hut. But, they are placed in fixed locations, so I'm not sure how they could overlap.
