Goldnight Castigator bug

Goldnight Castigator does not die to Inner Struggle. He should, as he is supposed to take double damage. Inner Struggle deals his power in damage (8) and Castigator’s toughness is 16. Instead, it only does 8 damage to him.

Some people reported casti gator taking only normal damage from all sources but in exchange making to take 3x damage(instead of 2x).

If that is true the problem is casti gator in itself and not the interaction with inner struggle.

My opponent took double (not triple) damage from gravemist but Goldnight Castigator took normal damage.

Yes, that’s what I’m saying, that Castigator is not taking the appropriate double damage.
