What you were expecting to happen, and what actually happened?
In my Arena game, the Sacrificial Priest on the opponent’s side sacrificed himself and triggered the “Summon Abhorrath” part of his spell. The animation of the summon occurred but the game carried on (ended) as though the summoned creature didn’t actually exist. As a result I won that match.
What are the steps to make it happen again?
I don’t know, it only happened that time and I doubt I could re-created the conditions to make it happen again.
Do you have any screenshots or video you want to share with us so we can see the problem? Attach them to your post!
I have archived my play session going back over 1h 40m before this happened. For now here is the snippet, more available on req:
