Favorited Fruits can still be stolen with Take Player’s Fruit developer product.
There is a small chance (around 1%) that a favorited fruit fails to get stolen, giving the player a message "Steal Failed (+100c)" instead.
Plants can still get mutations while favorited, but with a lower chance.
Despite it being Divine, it is always in stock.
Currently there is a bug that makes unfavorited fruits will be favorited upon re-entering the game, and vice versa.
It is possible to disable the heart icons from showing in the settings menu.
