Bug Mission Level 16

Hello, I have a problem with a Majin mission in the Glowing Village of NPC Pikaria, the thing is that I have to move a caravan and apparently I have to defend it, but it reaches a point where it stops and before reaching That point there are more caravans then the caravan that I have to defend is superimposed with the others that are bug and does not let me advance with the mission, I would greatly appreciate how to pass it or if they plan to fix it: c ... I do not like to leave missions without Do ... help please

Yes, I forget the mission many times to see if it was fixed, but nothing happened, and now that I remember there is also a bug comes another caravan after which the mission asks me to continue, but it stays still at the same point Of beginning while the other makes the way, clearly I follow the one that moves but independent of that I forget or do not forget the mission always the caravan this bug in a point of the route where it does not advance more, it is a stop that is between Glowing Village and Lost Waterway

It's possible this is just one you can't finish. There are a lot of Majin quests that are bugged and unable to be finished atm. Have you tried forfeiting it and then retaking it?
