Hello) Last times i wolk in Orkhem & Grafu. Strangely enough, this mostly happens on mob groups. And not always, in the same place. And most importantly, before the battle starts. I start running towards a group of mobs, without taking any damage yet, and my ally disappears. If I get a chance, I'll make a video and add it here.
By the way. It doesn't matter whether these skills are enabled or not.
