This place:
When trying to send the group to the Waystation (from Stack) I notice a (utterly annoying) loop in the path.
Using the saving game (https://drive.google.com/file/d/1sq7mHP ... sp=sharing):
1. Select all members in the group "Thieves";
2. Using the map, send them to the Waystation (south east of Squin - the one in the screenshot).
Sometimes they can break the loop and reach the Waystation, but normally all three keep going back and forth in the marked area.
