hi, on startup: "Error while running setup for entity prototype "QHP-epic-bob-heat-pipe-2" (heat-pipe): next_upgrade target (QHP-epic-bob-heat-pipe-3) must have at least 1 item that builds it."
can you please fix it?
Same here but for 5D: "Error while running setup for entity prototype "QHP-epic-5d-heat-pipe-02" (heat-pipe): next_upgrade target (QHP-epic-5d-heat-pipe-03) must have at least 1 item that builds it."
