Hello, I am having an issue with feast buff bonuses. Upgrading any of the farms does not improve the feast bonus. For example fowl farm should be giving +3 melee dmg after built, +6 at first upgrade and +9 after "2nd and final" upgrade. However no matter how many times I upgrade the building, the bonus stays at only +3. I tried reloading the game, restarting, activating the feast to see if it changes, but none helped. Also, the game is giving me an option to upgrade the fowl farm a 3rd time and spend the resources. However 3rd upgrade should not be possible as far as I understood.
