When pawn has "decent dining room" moodlet and eats in better dining room eg "very impressive", moodlet is not updated, rather old and outdated "decent dining room" moodlet gets refreshed to expire in 24 hours.
That results in thing like colony of 8 people having one dining room, but 4 different dining room quality thoughts, which is rather mess, than reasonable situation. That can stay for quite a while and require historian to know when dining room was slightly impressive, impressive, very impressive, etc. But rather we have Alice remembering how good dining room was week ago, Bob still thinking about how nice dining room was a quadrum ago, etc.
Thank you for the bug report.
