I dont have the cures to your problems but I can offer a couple of explanations. The dish washing problem is easy to solve, they (EA) could make bathroom sinks with no 'wash dishes' in the tuning, but they don't. It's very simple in fact so simple even I can and do delete this instruction on bathroom sinks. Using the furthest toilet can be fixed by giving all sims the Steel Bladder Trait, using reward points or whatever they are called. Make sure they use the toilet just before you add this so its working straight away.This works when you are playing them but if you leave them and return they will undoubtedly need the bathroom (and be hungry, tired and haven't talked to anyone despite living with 7 other sims). I can't play without this trait it saves so much time and trouble. Pretty sure the programming cant tell how hungry a sims is, sometimes they will wait until in the red to eat and other times they are pointlessly grilling stuff? I also try and give all my sims the neat trait but after an update last year this has added some of the most annoying behaviour I have ever experienced and causes cleaning loops by NCPs that I can only stop by debugging them, only for the fools to start scrubbing again. (I dont have the dirt & dust pack.) I tend to drag plates into the sink when they are left. I have not seen my sims ever choose a sofa to sleep but that's maybe because I always click the bed and send them to sleep, I'm a self confessed control freak. I hope a little here has helped. 👍
Yeah, I love the Steel Bladder trait, especially in saves where one of my Sims has the recipe for Snaggle Fluster. It does get rid of the happy buff from the bidet, though, but for that poor Secret Agent (who has since changed careers) it would have been worth it!
