Two cases, both probably with more than the listed schematics lost, but only able to verify these based on what I actually have equipped on self or companion that says "Made by <character name>" on them.
What class are you? Mercenary
What is your crew skill? Armormech
What was the name(s) of the specific schematic(s) that you lost? Critical Tempered Mesh Armguards
What class are you? Jedi Guardian
What is your crew skill? Synthweaving
What was the name(s) of the specific schematic(s) that you lost? Redoubt Reinforced Fiber Armguards, Redoubt Heavy Thermal Handgear
Thanks for your work in investigating this problem.
