I have to say though, even though this happened to me way back, what do you expect them to do about it? :/

The only option they have to fix this is to do a rollback on your character, making you lose all progress. Despite them not acknowledging this as a bug on their end but rather user error, and thus not issuing a rollback,would you really still want to?

I made note of mine somewhere december i believe. Since then i not only completed the relic quest for that job once again merely a week later, i also did 2 more relics on top of that and leveled all my other crafters to 50. Surely i dont want to see that progress ruined now. Was i upset about it at first? Sure. I was at Titan and it was hard back then :/ Now it's a cakewalk and not worth losing all your time and work over.
