Sometimes enemies spawn behind fences causing them to be difficult or impossible to kill. This causes my companions mainly my Spriggan to stand there for the entire Monolith.
Sorry about this! If you press “A” you can select a target for your minions, which can be an enemy or a place on the ground (though the ground will have to be out of range of the enemy behind the fence).
If you encounter any enemies that spawned out of bounds again, please post a screenshot and note the zone name. They’re easy to fix but screenshots make the process much easier.
Thanks - I will start submitting screenshots.
