The higher level feed depots have been changed to produce 1 feed, instead of the level number.
In short, this means a level 5 depot will consume 5 waters and produce 1 biennially feed.

The 'fair trade' values of feed were changed accordingly to allow higher prices when trading feed.

The 'fair trade' range price for tack has also been altered to allow values closer to what manufacturers have been selling for, historically.
