I've noticed a weird bug that affects Sims interacting (chatting).
When sitting at a table, they always prefer to sit next to the Sims they're interacting with. You can reproduce this by having 2 sims sit at a table with 4 chairs. Sit the Sims across from each other, and have them start chatting. One of them will move to sit next to the other. This is more interesting when you have a family of 3 sit at a table with 4 chairs and have them eat dinner together. It's practically a game of musical chairs.
Removing the extra chair(s) resolves the issue.
Not sure if this is a bug, per se, but it's weird to see Sims chatting, then get up mid-conversation just to sit next to the sim they were talking to. It would seem to make more sense that Sims could interact with any other Sim in any seat at the table without moving.
I've recorded a video of this, which you can see here.
I merged this with an existing issue which is basically the same although you described it differently.
