Hmm? I know the cause of the problem. This function is used after
experimentally adding a new building in the buildings evaluation code in
the AI. However, since we do not run generic_city_refresh(), the cache is
not updated, so we query the wrong values, making it seem like Harbour et
al do not confer any bonuses. So obviously we need a function that
bypasses the cached values.
