Do you mean that when you take a picture with the blueprint camera that it also saves it in editor as a composition? This can be done currently by placing the blueprint in a legacy map, then opening the legacy map in editor and selecting the composition and storing it.
So it appears as though the NPC Andre does not leave at night like the other traders. I don't even get the text that says "it's getting late. I'll be leaving soon" Nor do I get a welcome message. This isn't a gamebreaker, but I noticed that after several days of this it's starting to get really laggy in the area around him. I'm wondering if the lag is somehow caused by something in the NPC script.
