It's difficult for me to catch a screenshot of this, because I usually don't notice it happen until the end of a game. I rely on Empathic Bond to let me finish with full HP after using Miracle. But sometimes, Empathic Bond won't trigger at all, and I'll finish the game with 99 HP.
I'm not sure what's causing the bug.. It doesn't happen all the time. Maybe immortal? I usually use Anubis's ability on my creatures, especially the ones that show up earlier.
If it helps, here's the deck I use to battle Half-Bloods:
