Videoed it for you:
My list to raise from graveyard appears empty, even though I have the resources to both use his ability and pay the cost of the character. Am I missing something?
I saw the video and in fact, something is not right. I cannot test it now but will do it later.
Sometimes, when I have to bring something back from the grave by some ability effect (awaken or raise dead for example) I have to use the mouse to "right click" and hold the button pressed pointing at the center of the screen, and then I "push" the place where the card supposed to be for it to "appear", like you were seeing the cards inside the graveyard.
It works for me.
But I don't think this is your case... Do you know how to send the log for the support team? You could do it sending the video too for them to take a look.
