Wasn't sure if this was a glitch or some setting that I accidentally changed somewhere, but my mercenary won't follow me. He'll appear at my position as usual (such as whenever my Saliraptor lands) and charge in to attack (from across the map) when I give him the orders or get attacked, but when out of combat he just stands there. I tried hiring a new mercenary but it happened with him too (both are the mercenaries from Gorowyn).
you have the drop down tab on the merc window set to follow you I gather? Mine resets itself quite often to no follow
