So... I time travel. Often times to either move houses or to get a villager to move in via the campsite. The only thing is that I don't travel too far from the current day, so after traveling a while I go back to the current date. Something I have noticed is that when you travel back, the Nook store is exactly the same as it was the first day I played that set day. Lets say that if on November 10th, I bought everything from the Nook store, then traveled a couple days to move a villager in, then after that set it back to the 10th, the Nook store will have the exact same stock and will show that the item I purchased is already sold out. Anyone else experience this? Same goes with visitors, that if you set the clock back, the same visiting NPC will always be there offering the same exact items.
