Are those new hearthlings that you get with the daily update?
Or previous hearthlings that are perhaps working under or near the mountain and somehow they get teleported there?
Could you upload that savefile?
Find the save folder for the saves you wish to upload. By default, they are located in C:\Program Files (x86)\Steam\steamapps\common\Stonehearth\saved_games (assuming a default Steam install).
Zip the folder.
Right click the folder (should be a long set of numbers).
Left click on Send to in the menu that appears.
Left click on `Compressed (Zipped) folder).
(Optional) Rename the folder to something different than the default set of numbers.
Upload the save.
If the zip is less than 10 MB, you can upload it directly. Either use the upload button or drag and drop it into the compose window,
If larger than 10 MB, upload it to a cloud storage site like Dropbox, Google Drive, File Dropper, etc. and post the sharing link here.
I will investigate your savefile a bit more, but it looks like that part of the mountain is one of the spawn points you got, and since there’s no ladders to get down, they end up starving there.
I called the daily report a bunch of times, and some of the times the hearthlings spawned there.
