Stuck on Roadblock mission

I am currently on the roadblock mission.  I may have had to log out of the game while playing a couple times, and it seems I have messed up the mission.  I am supposed to escort pilgrims to the first shrine to cleanse it, but there are no pilgrim followers.  I reset the mission and clicked on the highlighted object at Pilgrim's Retreat, but no pilgrims appear to follow me.  There is a purple icon on the map that shows the roadblock mission next step, but I have no pilgrim followers to protect along the way, and when I go to the location marked on the map and enter the area, there aren't any of the usual icons showing where I am supposed to go in the area.  It just shows the icon for the roadblock mission back at the entrance. The game says that if I abandon the mission, I may not be able to obtain it again, so I have not tried abandoning the mission yet, because I don't want to cause a problem.  Copilot suggested I change instances, but when I try that, it says I can't as it is depopulating.  This is a class mission, so it is important, and I don't want to mess up the mission order.

Any suggestions will be greatly appreciated.
