As @talamatur said, a save game where the Hearthlings are stuck would be appreciated.
To upload a save, locate the folder in C:\Program Files (x86)\Steam\steamapps\common\Stonehearth\saved_games (assuming a default Steam install), zip the individual save’s folder (not the entire saved_games folder), and upload it. If the *.zip is less than 10 MB, feel free to upload it directly to the Discourse. If larger, please upload it to a cloud storage site like Dropbox, Google Drive, File Dropper, etc. and post the sharing link here.
Not sure a save should be very helpfull, except if the pathway is saved as well and not computed again when loading a game. And my guess is of course for the later one.
I do currently not encounter anymore this bug, I guess it has been corrected in the dev-2865/2867
