Xorxes have a valid point, I am just not sure if the mass claim is better done this EON or the next. For two reasons, first we need all people with unknown items to claim at EON and considering Vecna's and ND (and Worcej if you include him), it's unlikely to work.
Second point is nurse is only used when it did a save and if it's not used tonight and we mass claim, it's lost as scum can roleblocked it forever.
Have you considered this drawbacks?
