LuaItemStack.build_blueprint failing

[scruffyvoltherder]

This function should create a surface, and then paste the blueprint from bp_string. It creates the surface just fine, but there aren't any ghosts on the created surface. surface.create_entity works, build_blueprint doesn't. Any ideas what's happening?

Code: Select all

function PLCbuilder.plc_surface(force)

   local surface_name='PLC-event-surface-'..force.name

    if game.surfaces[surface_name] then
        return game.surfaces[surface_name]
      end
    
      local surface = game.create_surface(surface_name)
      surface.generate_with_lab_tiles = true
      surface.always_day=true
