Okay, on further playing, there are some issues here. The stove that is covered by the counter is often where the meals get put down, and I have to move the stove to get at the meal a lot. There's also a pathing issue in the red bedroom - my sims can't get to the side of the double bed that's half a square away from the left wall unless I move it. Other than that, I think all the pathing is fine.
