When using the CreditNote API. A get using the CreditNoteID returns the line array, but when you use a WHERE clause it does not return the lines array. Having said that, it seems to be intermittent.

Yesterday I was able to do both these with the same ID:
a) GET /CreditNotes/{id}
b) GET /CreditNotes?Where=CreditNoteID={id}
And they both returned the lines[] array.

Today, only (a) works to return the lines[] array.
