Corrupted 75 map to "unidentified" 123% items no map mods?

This is the second time this has happened. The first time I thought it was a fluke, so I did it again with the same results. Someone also reported this over global so I know I am not alone.

I set quality to %20 on a level 75 map "plateau". Then I alc'ed it, it came up some pitiful %70+ item business. Then I vaal orb'ed it to corrupted and it changed to "Unidentified". I used it in my hideout's map device. When I entered the ap it was %123 items. I started walking through the map with zero problem. I checked all my stats, all fine. No curses. All the mobs were all fine, didn't seem like extra damage at all. The only thing I could tell was they fractured. That seems like it was the ONLY map mod.

I'm not sure if this is expected, but I know this has happened at least three times now, twice with me and once with some other person.

The item drop did seem to be elevated, but I don't know if it was %123.

Oops, I just remembered, it was twinned boss also. Just Fractured and Twinned were the only two mods it seemed to have.

Unidentified maps give +30% quantity when activated.
