Conversations (flirty, humorous etc.) does not reset

I have noticed that different kind of conversations does not seem to reset anymore, for example if I two people have a flirty conversation and then stop talking, the next time they will talk the conversation will start off flirty. It does not matter if days have gone by, the conversation does not reset from the last time they talked. This is making it very frustrating to have group conversations as they often now start of with an awkward encounter, because a third sim is trying to have a conversation with the same sims the next day.
