It might be just me but I'm noticing sims are choosing to be mean a whole lot more often since the November patch. What I mean is, they are spamming mean interactions after choosing to be mean the first time. This is even affecting good, outgoing sims. Sims with traits that doesn't allow them to mean as much as an Evil, Snob or Mean sim. XD My Sim developed 100% negative relationship with 6 Sims all caused by the 6 Sims.
