Unblockable Symbol Graphics Disappearing

@Brigby whenever a creature with the unblockable symbol appears, the graphics disappear and a white  square takes its place. You can still tap that square and a pop up of the creature appears with complete graphics revealing what I am fighting against but once I tap to reduce the window the problem reappears. Thought I'd let you and the Devs know. The same problem occurs if the creature gains unblockable too.
