Bugged? What happened to it?
If they moved it, that may be nice to at least get it off the list, but I'd prefer they just restore it with restrictions so we can get it. It would at least get some mats into a black hole, which I think was the goal of it anyway. If they put clear guidelines on it then it should work. (i.e. Only those who did not complete the achievement can donate a LIMITED number of mats - just enough to complete the achievements, then people who want to complete it can and those who don't care, can just leave it alone.)
