v.08.1 has released, hopefully curing what ails ya. Farm seems to work now and not give ridiculous milk, so that's good. It'll likely be fully revamped soon anyways, but working for now is better than not working at all!

I actually just had one of my cows still give 1493 food from milk and she's only got huge boobs and milk flow 2 with no other farm upgrades. All my other cows are reasonable numbers although none of them do have any milk flow modifiers.
Also looking at your code i saw this which doesn't seem to make sense.
var chefhelped = false
if chefmod > 0:
chefhelped = true
else:
chefhelped = true
At that point why bother with the if? Just set it to true
