I had almost 1000 lingots and now I only have 26. I didn't purchase anything in the lingot store, although I was planning to purchase idioms. On my home page, the "idioms" bonus skill appears, but it is grayed out and not linked to the idioms bonus skill (it's not linked to anything). Also, when I go to the lingot store, the "idioms" bonus skill is listed, but the button that says "get for 30 lingots" is grayed out. What happened to all of those lingots I earned? It's not like just a few lingots disappeared. Very frustrating.
