Attempting to even distribute quality affected ore across multiple furnaces, and it stuck full stacks into the first few furnaces rather then distribute as expected, which it does with normal ore.

Yes, I can confirm that

Quality items in general appear to not work with distribution. Ammo into turrets, ammo into furnaces, science packs into lab, etc etc.

I've noticed that as well. Quality breaks Even Distribution.

Quality (and any other additional item data like spoilage or durability) is not supported yet, so it reverts to the vanilla way of distributing. I'm still working on a fix

Fair enough! Quality seems like a massive wrench in the works for everyone to deal with, doesn't surprise me too much it'll take some time before it's fully supported.

Thank you mod creator!
I really love this mod, it is in the must have category!
Waiting for the quality-even-distribution update!
