Bugged maps with thousands of IIQ, IIR and packsize (can possibly be mirrored with beastcrafting)

Saw this map with thousands of IIQ, IIR and packsize linked in chat:



I'm not sure if the map works like the tooltip says it does since I don't own the map to test, the main problem is that non-unique maps can be duplicated with beastcrafting so that makes those bugged items extremely gamebreaking, differently from the bugged unique items created recently that cannot be mirrored.

You can also find other bugged maps on poe.trade (http://poe.trade/search/orasarahokitet) if you look in the right places. I'm also linking the screenshot in case the item is removed from poe.trade:
