[Open] Party guests appear on the far ends of the sidewalk

For the invisible Sims, we have a bug report: https://answers.ea.com/t5/Bug-Reports/Open-Very-few-sims-visible-at-parties/td-p/8798671

Are the Sims at your parties all at the far ends of the sidewalk?

Yes. The sims are at my parties all at the far ends of the sidewalk.

Hosted my first party at Edgewater and related to this issue with guests standing on the sidewalk I have to say that the enter/exit spot of Edgewater is so far behind the trees on the left side of the lot, that it was difficult to click the guests back to the party because the guests are hidden behind the leaves.

I am also reliably experiencing this issue at every party I have. Sims begin attending the party, then quickly appear in clumps at either end of the sidewalk the minute I go into a menu, an event or offline, and will stay there for 12 hours if I don’t go out there and interact with them.
I have stopped doing that. It’s been almost a year now. At my last party, and I don’t throw many anymore, I started inviting chosen Sims in through interactable items in the house and just doing relationship events. Until I realized I’ve talked in chat before, that person was possibly live. That and continuing with my backyard design. There was nothing else to do.

My parties are not advertised. At least not to my friend’s Apple Account.

No one is announced at my parties. All of a sudden there’s someone in the house, and I have to check chat later to see who it might have been. No idea if friends are showing up. I have missed even saying hello to people on my friends list before because sometimes they show up later on and I’m not checking chat. 

My passive Sims show up after my first departure from my parties. Recently I had no properties but my base at Emerald, and my Sim’s infant baby showed up in his crib, alone on the second floor. He laid there, defenceless, for 12 hours while the house was open season. I did have his mother sitting with him. But I wasn’t there for most of it and that wasn’t fun at all, actually. 

My interactions only go one way. I can go to an interactable item, like ‘Play Party Games With’, at the A la Mode Dining Room Table, and call in 3 Sims, but they will never interact with me. Or so it seems. I once asked a party guest to come up and talk to me at an agreed time and when we confirmed it all I’d seen was her across the room.

I am constantly transported to other locations in the house. No matter where I am, as soon as I click the pink menu to ‘make friendly introduction’ I am teletransported to another room, even upstairs or downstairs, even way across the house. This is extremely confusing when at other people’s party’s. I never know where I am. It is exactly like when you click the pink button to ‘Begin Hangout’ and you are transported to your front courtyard area. Recently this one has improved. And that’s huge. It’s been doing that for a long time and at my house I could handle it, but elsewhere, as I said, it was disorienting.
 
That’s all I can think of for now. Wish someone would have a look at some of this stuff. I really love this game, I do, I play it all the time, I spend countless hours decorating!! But I’m getting really tired of working around all this. Really. 
@Ilois4 where is Edgewater? Is that the lot with the fountain? And also, is the hanging out on the sidewalk issue your only one, or do you have others?
Edit: I have found out from other members that the answer to that question is no, it is usually not the only issue people have. 

This bug has been going on for years. When you leave your party you are hosting for any reason and come back they will be at the edge of the sidewalk. Just click on them and they will go back to normal. Like I said this bug has been going on for years and still not fixed.
