I think I found a bug in the farm. Not game breaking but a code mistake. While trying to fix a parse error (One that I did while playing with fire on the scripts trying to make a compatibility patch) I found something quite interesting. At mansion.gd:
At the else, I presume that chefhelped should be false (since chefmod should be 0). Idk if you have noticed it yet. Also, at gold generation (at the end) I added a 1/10 modifier since I think wining 1000 gold per milking slave was a bit too much. I dont know if it was intended or it was another bug but anyway I posted it here in case it helps you. Keep your great work!
Edit: Ignore the obvious parse error on milkproduced, that was the one I was looking for :D
