This looks like a similar issue. Around 17:08 in the video.
Note how the carpenter (or maybe it’s the farmer*) comes to pick something up and at that point the two eating workers pop up and start floating, where before at least one of them was sitting in the chair as intended.
(*) Difficult to say, as they look identical, literally. In fact, I had two identical pairs in this video (for the other pair, see 5:07)! First time I’ve had that happen at all, never mind twice, never mind after having many new looks introduced! Funny.
