Star 2.2 miracle construction conditions

If it is to repair the destroyed wonders (up to three in the Milky Way), it needs science and technology and huge projects (pre-science and technology: battleships, Acropolis, zero energy).

Each galaxy can only have one giant building at most, and each empire can only build one giant building at most (except habitat and stargate, which can be built at the same time). Note that there can be multiple orbital habitats in the same galaxy, and the stargate can be built in a giant galaxy. There are two ways to achieve miracles. Repair the damaged wonders and build them yourself.
