Active DOF Error

aoav160

When trying to add a Fabrication Engineer to Active Space it says: "[Inventory] You cannot equip more than 1 items of that category". But the only other Fabrication Engineer is that is active is located in Active Ground. When I remove the Active Ground Fabrication Engineer the Active Space Fabrication Engineer can load. Do the Active Space and Active Ground count against each other? Ticket ID #4,597,010.
