What you were expecting to happen, and what actually happened?
Most of us are familiar with dust devils bug where casting his spell kills some unit but doesn’t remove it. You still can win the game even with those troops still on the board, they are just like ghosts, don’t gather mana nor they attack on skull matches. But what I noticed that when I finish the battle I don’t get souls for those unkiled troops. I was farming for trait stones with 4x dust devil and noticed i usually get 7 souls after every battle. But when there’s a troop that remained on the filed i get only 5 souls (and once i got 4, while 2 troops were remaining). Just wanted to point this out too.
What are the steps to make it happen again? Try it it’s not hard to make it happen.
Do you have any screenshots or video you want to share with us so we can see the problem? Attach them to your post! No need.
