I remember, after reading her description, I thought at Artifact Search... so, I bought her, skilled her and sent her out for 5-6 times (speed up with gems, all took like 15 min). She always came back with rainbows.

About quantities... I suggest you take some printscreens with the search results and fill a ticket. Even their answer will be 'it is a known issue, we are investigating, thank you for your patience bla bla bla' they will have to ... well... investigate and register the complaint.
