Sims don't auto-group/can't do group interactions

Same here. Ever since the Reaper's Rewards patch, my Sims can't be seated together when they go to a restaurant as a group. Doesn't matter if they are family or friends. The Sim who requests the table is the only one who can be seated at the table. The rest of the group can't sit with them, and the game treats them as if they aren't in a group.  Similar to the date bug, but this affects families and friends.
