[FIXED] Townies walking by that stop to chat always use hostile greeting

This is happening in my game too, every time two walkby NPC's stop to talk. They will initially do the angry, hostile greeting, then proceed to greet eachother normally. I can't really say when this started happening or even when I first noticed, I usually don't pay too much attention outside my sims houses. I was thinking it was intentional, so that children could increase their Empathy and Conflict resolution values, mediating between the two angry sims.

I see this behaviour in every neighbourhood, in every save.
