You have discovered a border case EA's developers haven't thought of. This is a bug, but so far you are the first one that encountered it, or at least I haven't heard of anyone.

You need to contact EA, they can fix your town. Alternatively you can wait for an in-game update fixing the issue, but I doubt that there will be one if you're the only one who encountered this bug.
