This I think is one of the most useful changes to the Foundry to come with this update. Objects can now be treated like NPC contacts. You can have the player use an object and have a dialog popup which can have a success or failure. Puzzle makers rejoice! No more reskinning NPC contacts as consoles or that annoying "Talk to Console."
I remember in the past people have had problems where an NPC contact would die and then you couldnt talk to them. I havent tried it, but can you skin objects as NPCs? If so, then by doing that and using this dialog with object NPC you could create unkillable NPC contacts.
