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.

Product: The Sims 4
Platform:PC
Which language are you playing the game in? Spanish
How often does the bug occur? Every time (100%)
What is your current game version number? 1.109.185.1030 DX11
What expansions, game packs, and stuff packs do you have installed? Get to Work, Cats and Dogs, Seasons, Discover University, Snowy Escape, Lovestruck, Outdoor Retreat, Spa Day, Dine Out, Vampires, Parenthood, Luxury Party, Perfect Patio, Spooky Stuff, Bowling Night
Steps: How can we find the bug ourselves? Send more than one sim to anywhere (using travel option, map, road click,.)
What happens when the bug occurs? Groups are not formed autonomously anymore
What do you expect to see? When I send sims to another place (like a restaurant or a park) a group formed autonomously like before the last patch
Have you installed any customization with the game, e.g. Custom Content or Mods? No
Did this issue appear after a specific patch or change you made to your system? Yes, last patch (September)

When there's a social event like a date, the group is autonomously created, but not when you travel with another sim, this is specially annoying for restaurants cause when you request a table you need to remember to form the group before doing it or you will be seated alone.

Done, if it takes account what other people said in the other threat it should be Stuff Pack related

@crinrict 

So, I tried with all pack (except For Rent and Kits) and the problem still there, maybe it's For Rent?

O maybe it's something else..

I didn't complete reaper event, for more information.

• I'm experiencing this same issue although I haven't tried this with restaurants but I'll have a household full of sims travel to another lot and once the lot loads, they are not automatically grouped, which forces me to do it manually.

Yes, I have mods.  

I did try that and still it's not working.  You can't seat them together.  One sits there and the others just roam around.
