I've lost the Assassin's stats for five armor pieces and - I'm fairly sure - three weapons too. All were transmuted. Armor pieces are: Emblazoned Shoulders, Coat, Gloves, Pants and Boots. My Assassin's Emblazoned Helm was not reset. Selectable options available are: Berserker's, Knight's and Rabid only. The weapons were all Pearl Handcannons. My first slot weapon is an Assassin's Pearl Handcannon and remained unchanged. The other three - again, I'm fairly sure - were all Assassin's. However I selected Berserker's for all three from Berserker's (and two other options - probably Knight's and Rabid too) without really thinking. It looks like the first items in armor and weapons were skipped, but the rest were stripped of Assassin's, and now only have Berserker's, Knight's or Rabid as options.
