It is not. It is a super fun colour that makes people look extra special. Others might not be able to detect the speshulnezz right away, so using a different font than everyone else will make it undeniably obvious.
Your sims are babies for 24 sim days? And teens for 192? How do you entertain them for that long, play them for that long without getting bored?
I am all for the more realistic lifespans, and getting everything in tune to the seasons sounds awesome, but I would grow mighty sick of my sims before they finally hit old age and died.
Sometimes I like to stick a bunch of sims together in a house and see who hooks up, which is why I let them get on with their chattin' and flirtin' on their own (I have ACR installed). Other times I get fed up with them being so stupid that I just throw my hands in the air and let them kill themselves if that's what they want to do. And then sometimes I take offence at their stupidity and go, "Fine! If you don't want to do anything, then you can just bloody well stand there until you do!"
I do have Bathroom Uses You, I just thought that you had to set something up in game for it to work (and I've never really got around to that for some reason).
I haven't noticed Free Will turning itself off. Of course, I've never checked either. I rarely play with Free Will off so I didn't think to look. If it happens again, I'll check it out.
I found it very peculiar that it was never ALL of the sims that turned inactive, which is also a reason why I didn't check if Free Will was off. It did tend to spread, but I don't believe everyone was ever affected at the same time. I have all expansions up until Seasons, and I never noticed this problem before I installed Seasons.
I've seen many sims that at random times just stop using free will. They just stand there, doing nothing. Once their bladder goes really low, they do go to the bathroom, whereupon they clog up the bathroom. Occasionally they'll also go to bed when their energy gets low, and sometimes they fall asleep where they are. They don't initiate any actions. And then suddenly free will "gets turned back on" and they're back to normal.
I don't know what does it. I just figured I had a hack conflict somewhere or something, although I haven't had time lately to do research on that.
