Ive been playing the game for about 30 hours so far and have found all collectables and lit all bonfires. I decided it was finally time to finish the missions. However the shaman tells me to wear the mask of batari and ride a mammoth. I already rode a mammoth through the gate so the mission will not start. There is nothing on my map under missions. It's the last thing for me to do but I can't get it to start. Please help!!
