So to clarify, you did a mission, and no ore dropped. Then there wasn't a patch day where things like this are fixed, and you ran the mission again, and still no ore dropped.
That is correct. We killed Zlandicar, after it's been supposedly patched (based on the Devs I the "Trash dropping ore thread". and yet no ore dropped at all. It was just late yesterday that we killed him.
There hasn’t been a patch yet. Nothing changing until next patch which is January. So you have time to farm them off trash at high drop rate and then after January patch you can farm them in zlandi.
Fixed internally: Means they made a fix,and they now await a patch on live. As Vae wrote, there need to be a patch for it to be fixed, and since no patch, it is not fixed on live.
