Days Gone is a great game, too much repetitive, but still OK. But sadly, like every game, it has some problems and bugs. Even bugs that stop your progress in game.
When you are in the mission Tail the Horde, you have to follow Iron Mike around the Horde. But every time you come near the Horde, they see you and the mission fails.
How to beat the mission?
What you have to do is wait. Yeah, just do that. Before going near them, wait until they have all gone up the mountain. Make sure they are not on the road anymore. Now you can safely get up that hill while talking to Iron Mike and finish this task.
Sadly, the developers are not expected to fix it. This is your only solution for this problem.
