I presume DM_ is for Dark Master, the original administrator of the project. I suspected it could be, but I do not recall ever seeing elements with that prefix. I found the original release of LGNPC Aldruhn and the script DM_vevul is not attached to Vevul Alver. Instead he wore the new script LGNPCVenimGuardScript. All the latter does is declare noLore. That script has since been 'cleaned' from that NPC (very likely by me :blush: ). The fact that there were no consequences to removing the LGNPCVenimGuardScript may be why I felt it would be harmless. There were seven other NPCs that wore the LGNPCVenimGuardScript, but happily their dialog does not attempt to write to a phantom variable. Anyway, the line in dialog results has commented out so it should not cause anyone else grief after the next update of Ald'ruhn.
