Monster cards

• Pantheon monsters (they don't seem to drop at all)
  

Not sure.

• Kerning Square Parfumes (they don't spawn at all)
  

They were moved to their own map, on the map with the Kid Bunny Doll things, should be a teleport into a shop there.

• Queen Pepe, Toy Soldier (not getting these in the Silent Crusade quests)
  

To my knowledge were removed ages ago, Nexon has yet to update the codex to show that.

• Coco doesn't register, but instead pops up as a use item in my inventory
  

Pretty much same as above + the first time you fight him is bugged. They tried adding the USE item of his card as a reward to the quest, but the card doesn't register when used.
