NeutronWall Array problem

Created by: kkabita

If Neutronwall Array is used along with any detector configuration (like MUST2), all the branches in the generated root file of the other detectors show empty spectra, while in the absence of NeutronWall all are working fine. Is there any specific reason for this occurrence or this might be a bug?

Please suggest how can I use NeutronWall along with other detectors in the set-up.
