What you were expecting to happen, and what actually happened:
Blightwing’s card says that if an enemy is diseased when the card power is used on it, it will explode 3 green gems. If the enemy is on fire, it will explode 3 red gems. I have used the card to attack a diseased enemy and an on fire enemy, neither resulted in any gems exploding.

How often does this happen? When did it begin happening?
Can duplicate this as frequently as I can manage to use the card on a diseased or on fire enemy. Both times I’ve done this, the enemy I hit died. Not sure if that makes a difference.

Steps to make it happen again
Set enemy on fire or disease it, then use Blightwing on said enemy.
