Are we required to rebuild ever single building by all three tiers? If not, how can you tell if a single building was already made with a perfect build? For example, the chapel is a perfect build, but tier 2 of the range workshop needs to be redone to complete the achievement, how can you tell?
We only need to make ONE perfect build on any tier to complete that achievement once and for all. You can do it with any building, existing or new ones.
