Evolution
Does food left on Fat Tissue score at game end, or is it discarded when the trait is swapped out or the species dies?
The designer ruled the Fat Tissue exception was removed, which overrides the older rulebook text.
From the 3rd print run on, food on Fat Tissue always scores: when the species dies, when the trait is swapped, or at game end. Food gained on Fat Tissue in the final round goes into the bag and scores too. This corrects the older rulebook wording on the Fat Tissue card, which says leftover food is discarded.
