At this point, I'd consider the wacky bugs continually introduced to The Sims 4 as more of a feature than a bug. For example, a recent update turned previously placid Sims into moody, argumentative jerks who were constantly scrapping with one another. That sounds great to me, although if you disagree there's bad news. EA Maxis say that their fix, intended to release this past week, has been delayed until early December.
