I recall earlier on in the camps creation a ‘Smithing’ job appeared that had a 3 week timer that didn’t appear to be associated with any npc. Couldn’t do an emergency recall on it at first. After awhile this was available. Might have been the point at which things went awry.
edit: Managed a workaround (I think) by using a trench job to add the survey blueprint result. Hopefully that kickstarts things into motion.
