Beta: Temperature Machine

[potent merlin]

Hello! For the temperature machine do we need one for every barn/coop? Or just one for the entire farm? It looks like you can only buy it once.
Thank you in advance 🙂

one per animal building! all R&D at the lab is a one time purchase, once obtained you will be able to craft the item yourself in craft menu 🙂
