You can infinitely turn in sparktail's grudge quest after finishing it once, the moment you repeat the quest, the kill counter goes back up to 20/20

Ah yes, I think I see what might be causing that. If you complete it twice in one session it will not properly reset the kill_counts. Thanks for reporting! I will fix the exploit the next time updates get released
