Graill

I am on an LG V10 running Android 6.0 I have encountered this issue twice, both during the Flood mission. I encounter an Ogrekin (Monster version, not Henchmen) and he rolls his d4 causing him to return to the bottom of the deck after I act. I defeat him, he goes back. I run through the rest of the location and encounter him again. He does not roll a d4 for his ability, I defeat him, he returns to the bottom of the deck. This continues repeatedly until he is the last card in the game, and Black Magga eventually eats him, causing me to not advance even though I won the scenario. Both times I was using Kyra, Seoni, and Harsk, I don't remember which locations.
