A couple questions:
1. Do the DIY recipes and purchasable furniture (such as the lighthouse or the solar panel) from Nook Stop change daily? (I ask because one of the first fence recipes I got is no longer accessible to generate even though I never redeemed the recipe)
2. If you put a villager on the second or third tier of the island, will they use a ladder to get down or will they be sequestered there until you put in ramps and/or staircases?
3. What are the requirements to unlock the Island Designer app?
4. Does K.K. Slider only play on Saturdays like in past games or does he randomly show up now? (I just got my Resident Services building today and already set up the campsite plot to start the process of unlocking him)
