Old Guns Quest issue, not the one I see everyone else having (can't build artillery)

So, having issues with Old Guns, can't build the artillery. I have the components, I try going to where the artillery was (I already scrapped the ruined ones if that makes a difference) and nothing. Don't see the outline to build like you do with other objects. I tried opening the Workshop menu at the locations AND going to the Workstation
