"Visitors are leaving" message spams the console infinitely
I ran into a particularly nasty bug, but I'm not sure if it's due to my own fault or not. What happened is that I had a visitor from a friendly faction, but he wouldn't leave even when the message appears saying that he was leaving.

He stayed there for days, wandering my base and not fulfilling his needs. Finally I had enough and used dev mode to "pass to world", which removes the pawn from the map without killing them. I used it in the past, and all was good for a day or two. Eventually though, the "Visitors from [insert faction name] are leaving" message showed up, but it started spamming in an infinite loop.

Nothing I did could stop it, even after restarting the game and reloading the save. It seems like the save file is bugged now. I assume it happened because the game is trying to find a pawn that no longer exists on the the map. The weird part is that I played the save for 12 hours so far, no visitors had this problem before. I saw no other warnings or errors in the log, just this one:

Sorry for my late response. Somehow I must have missed writing a response.

It sounds like the visitor bugged out first, but when you removed him, the visitor group lord broke. What you could do is edit the save game (make a backup first!) and find and remove all lords that are active. You shouldn't have any groups / caravans or parties at that time, though.

*bump*
still appearing. even if you weren't in dev mode at any point of your "campaign", still, it can appear. the message starts popping up, they won't leave and then you got the infinite loop again.

The thing is, the group lord will only try and leave the map once. If something fails then, it will stay forever.
If you remove all pawns from a lord it effectively breaks it. So you can better edit your save file and remove the lord there first.
Or even better, when it fails to leave the first time, load the last save.

A bit of a Necro, and you've probably moved saves, but I have a solution that will help anyone who stumbles here with this problem in the future.
The problem stems from "Pass to World"-ing a guest pawn, trapping them in an eternal loop of leaving a map they are not on. The solution is to bring them back.
  1. Go to Dev Console and go to "Spawn World Pawn".
  2. If you're lucky, you know the name of the offending pawn, the one you passed to world.
  3. Find the pawn on the list, click, and click anywhere on the map to bring them back.
  4. If you don't know the name of the pawn, you'll have to trial-and-error the (potentially long) list until you find the right one.
  5. The pawn will leave the map and you'll stop being spammed with messages. :steamhappy:

Interesting angle! If they're off the map, why do they get updated, though?

Oh, I meant "Map" as in the Local Map.
When they're off-map, (I assume) the game keeps ordering an object (the pawn that was passed-to-world) that doesn't exist because it's not in the local map.
So when you "spawn world pawn" you bring them back to the cell so the game finally has something to order. They simply walk to the edge, like the error messages wanted them to.

Yeah, I get it... I wonder if that's possible, though. I don't think unspawned pawns get updated... They might store their last duty, though, which can be to leave the map.

2 years after, I have the same bug. And Silver Felyne's way of fixing it is pretty hard.

There's a dev action now, "Remove broken groups" or so. Try and see if that works for you.

Can't find that dev action, where should I search?

Oh, right -.-
My bad. It's only available in the new version that isn't released yet. You can download it here: https://github.com/OrionFive/Hospitality/archive/e1f31e9117d591a03f28d40b0e7680674046f6f1.zip

Bug persists. That "Remove broken groups" debug tool doesn't work at all.

Then you'll have to solve it some other way.

I tried removing the mod, entering my save. Saving, and then putting the mod again.

Now visitors get in the settlement, and just stay around anywhere, while dying from hunger and doing absolutely nothing. Not even eating the food they have in their inventory.

...Yeah, you should fix this bug.

The problem is, it's not a bug. Your savegame is borked.
