I can't remember the quests name, it was a quest from the elders where I had to help her prepare a speech, as part of this there were 3 options to choose a bonus from. I chose the one that gave me -10% Need consumption for the Shepherd, but instead of reducing how much they consume it limited their needs to 90% maximum, where I now have no Shepherd resident full, with too little workforce and no possiblity of upgrading any shepherd until the "buff" runs out after 30min.
