Exactly TG. Before you would get random mummitomium, plutonium, platinum, whatever and maybe even ONE bar of iron. Now it's a huge, and worthless, stack of iron. So here is what I've found with what I had, (and it was more than I thought I had). With gems the normal get a skull or get a large cut is the same. With single stacks of random metals you get compendium. It doesn't seem to matter if you have four of one metal and different amounts of other metals. If you put in one kind of metal only, you get a large bar of that metal. So nothing has changed there. It is only when you stack more than one high that you get a problem. I have not tested it with maybe one stack of something and all the rest singles but no more getting several compendium at a time by stacking metal bars. I also did not test large bars stacked though I did test single layers of large bars and got a large compendium.
