Sometimes, when I summon/sacrifice a couple times, Sacrificial Priest will not fully sacrifice a card : the card will die, but not disappear (it graphically remains on the board, but when I click it, it has 0 health).
It may look like it’s only a graphical bug, but then, I can sacrifice the half-dead troop. It won’t add it’s attack to the spell damage, but it won’t remove it either, unless it is replaced by an Abhorath.
I have a screen shot on my phone, but I’m too lazy to retreive it from it, so if I can reproduce it on Steam, I might upload it later on…
Edit : Here it is.
This was my initial team.
Then I sacrificed Mercy and got an Abhorath. When I sacrified Abhorath, I saw Mercy back (but unusable, except as target for Sacrificial Priest)
