Mines kind of stupid. It took me over a year to discover that you could refurbish with a shirt or dress. It's stupid, because there's a clothing option given, but for some reason I thought it had to be clothing that you designed yourself. Boy did I have fun refurbishing with a bunch of different shirts, after my silly brain figured it out.
I wasn't aware that you could sit on rocks after the Amiibo update was released and it took me by surprise when my mayor accidentally sat on one as I was moving her around. Thought it was a glitch.
Um....when you walk down a beach ramp, campsite, or dock you can trample flowers...
Lol for the longest time I thought you couldn't get rid of stumps so I just never messed with my trees, ever...
i didn't even know i could talk to villagers until i was well into the game (about 300 hours.) i thought they were just there for no reason! i really feel stupid now haha
