Possible typo in the sidequest "Problematic Pests"

EDIT: DISREGARD THIS POST

The quest uses the word "extant" in a spot that felt out of place. The exact wording escapes me now that I have completed the quest, but if I remember correctly, either the word "extinct" or "existent" would fit the situation better.

EDIT: Disregard this post. Turns out extant IS actually a word. This game always finds a way to sneak some new vocab into my life

For posterity, it may help to explain that extant is the opposite of extinct. An extinct species is one where, to the best of our knowledge, all members are dead. An extant species is one where there are still living members.
