Hi, I am trying to do some "Balanced Trillium Ingot" which needs the "Plans: Balanced Trillium Ingot and Its Uses". I get the plans (after searching a lot) and I learned it. I make my ingot and I logged out (because you can make only 1 x day); a the next day when I tried to make another, I realized that it wasn't on the list. So yesterday I repeated all the process with the same results. Conclusion I think that the plans are bug.
Waiting for an answer, because it's the most important material for a blacksmith (epic items lvl 553+)
