• New Daily Task: Nightwave: Complete daily Nightwave acts. (Closes [Feature Request] Daily task for nightwave #76)
• Fixed typo: "Paladino" → "Palladino". (Closes [Bug] Typo "Paladino" should be "Palladino" #73)
• Reworded weekly_nightwave_complete to say "acts" instead of "missions", because that's what they're called in game, and not all acts are missions.
• Added test: task text should end with a period.
  • Added period to daily_kim_parent and weekly_ayatan.
