In the current April PUP version, Spanish gain access to the Hacienda by sending the new card ‘Viceroyalty of New Spain’. But apparently, this card is too powerful when used in combination with the Spanish herdable animals cards.
These cute sheep work as efficiently as ordinary villagers when you configure the Hacienda to produce villagers or Soldados
I think this is too powerful beacuse players can easily get 2 Haciendas and then send 15 sheep to boom quickly. These 15 sheep are almost equal to 15 villagers.
In addition , the homestead wagons can also build haciendas, which means that the Spaniards are alomst unlimited in their use of sheep to boom. You can even send infinite 1 homestead wagons + 7 sheep to keep building haciendas.
I don’t know if this is a bug or if devs did it on purpose
