Have u by chance changed the save name? the survivors data is saved on the mod folder with the same folder name of ur save so if u change the save game folder name they just wont be there.
Tho, theres plenty of other reasons for that to happen including bugs so idk for sure.

Oh, I forgot to update this.

After testing a few times, survivors acquire a "MIA" status when you put enough distance between you and them.
When you are away from the survivors, they freeze in place and stop showing up in the map, acquiring the MIA status because you can't see them. Once you get back to them, they start moving and showing up properly on the map and the survivors list.

If you happen to quit the game when you are away from your base and then continue, no survivors will show up on the map and clicking the button will cause LUA errors to start piling up rapidly.
It goes away once you return to the base, exit and go back in ^-^

Happend to me i logged out far away and all of them vanished.... now i have no npc and cant get them to spawn....

Is there anyway to recollect them? I have them missiong for awhile now and dont know where they been
When I try to order or check information on a MIA survivor, I get an error, when I open the map I get constant errors notify on the bottom right of the screen

♥♥♥♥♥♥♥ thank you! This was it. I changed the name and they disappeared, but I didn't realize it because I stopped playing for a couple months. Once I figured out what was the name before they popped right back where they were.
