I had an issue with my party not fast travelling with me from camp to a destination when I used the portal to do so. My work around was that if I use the bedrolls to exit the camp, then my part came with me. Not sure if this is just a quick way to travel by yourself without having to individually tell your party members to chill. Enjoying the game so far.
Similar bug.. traveled alone and to a location I hadn't been to in hours. I clicked on leave camp and ended up in the Swamps instead of back where I started. So reloaded and tried using the Bedrolls again that didn't work either.
Same, if I get dumped back where I was before camping after resting overnight everyone gets dropped back, but if I fast travel from the camp during the day, every character has to travel separately
