I am missing three master forms after the maintenance.

Master Cure Poison
Master Group Cure Poison
Master Antidote

The patch notes say "Doc Tarrant will no longer sell Master level formulas".

At no place in the notes does it say that something that I purchased was going to be deleted and taken from me.

Further down in the patch notes:
"Formulas "Expert Antidote", "Master Antidote", "Expert Spell: Cure Poison", "Expert Spell: Primal Cure Poison", "Master Spell: Cure Poison" and "Master Spell: Primal Cure Poison" now call for Hunter Scorpion Tail Stingers instead of Scavenger Scorpion Tail Stingers to make the Tier 5 potions and spells"

That implies to me that the Master forms are still around.

Why were our master forms deleted? I bought it, I want it.
