When I try to investigate this item of evidence, all I get is Nick Stokes telling me to talk to Brass about it.  However, it never gets mentioned when I approach Brass.

The item, itself, never gets an evidence tag (not even grey, let alone red for complete).

Is this a bug?  Could this be the reason why noone seems to be able to get all 45 pieces of evidence (the best being 44)?

Thanks in advance,
Paul.
