Before any quests in Thessila are completed, going to the main menu via the Thessila location menu and then attempting to see the devout list will only result in going back to the Thessila location menu again. After doing this, attempting to exit to the Thessila map then puts you into the devout menu, which will now softlock the game as the back button no longer works to take you to your previous location. This softlock will persist through saves.
