Bug: Panther's Prey does NOT increase damage from Exploding Tech

JSP869

Panther's Prey: The Black Panther seeks vengeance. Choose an enemy and create a 3-turn Black Countdown tile. While this tile is on the board and the chosen character would take damage, they suffer an extra xxxx damage.  
  
I tested this several times on the 5* node and it never increased damage from the Exploding Tech tiles. It should have, because Panther's Prey does not specify that the damage must come from friendly attacks.
