-Pond smelt. Like seriously. I freaking hate pond smelt so freaking much, it's not even funny. Them and every other ridiculously common fish that clog up my rivers and oceans.
-Pulling trash out of the ponds and rivers and such. I mean, I know they're trying to send the message that littering is bad and it's good to pick it up, but as mayor, I already have to worry about grass deterioration, dying, flowers, weeds, lost items, etc. -- and I'm a housewife IRL. Plus, it's gross. I mean, it really is gross. Every time I pull a can or tire out of the water, I feel like smacking a villager with it.
-Placement logic. I mean, I know the game operates on a scale of one square unit per foot or something along those lines, but it drives me nuts that I can't place a PwP next to the wall, but Hans the gorilla can.
-Why doesn't Isabelle have a house? Is she homeless because if so, I'd be really upset. Heck, I'm upset now. She practically runs the town for me and she's sleeping in a supply closet.
