DESCRIPTION:
Checking the description of a future mutation that you already have at a lower level displays the description of your current level of that mutation instead of the level you will have in the future.

Easiest way to see it is on Vine Stalker, where the description for "You have extremely sharp teeth." and "[You will have razor-sharp teeth.]" is the same, the level 2 fangs description. Considering that normally the description of a future mutation is what you will have (say evasive flight on tengu) and not what you do have, it would make more sense if the latter displayed the description of level 3 fangs. Currently, to a new player, it will seem as if nothing will change.
