A small circumstancial display bug. Here's what happenned: -Ennemy wizard casts Firestorm -Firestorm hits my wizard (among others) -Firestorm kills ennemy wizard caster -A copy of the Firestorm card is attached to my wizard -Mystical Wyrmhide removes Firestorm attachment from my wizard and should attach it to the caster, but the caster is dead. So it is in fact removed, but a copy of the Firestorm card is still displayed on my wizard. I did not take the burning damage, and the attachment is still showed on my wizard next turn.
