Madam Vadoma - Identification issues

[Nemesis 24]

After handing in a couple of windows of goods to identify, and paying 1500 gold or so, a great deal of the items were not identified.  That part took a further five hundred.  Either way!  Seemed like a mistake, as everything should have been identified the first time.

Seems to be a limit on the amount she'll identify at once.
