Expected result: Having max skill Engineering 300/300, the object/quest giver Schematic: Field Repair Bot 74A should prompt the following Gossip Menu message: <Drawn out on this parchment is the schematic for a field repair robot.> with a clickable Gossip Menu Option for: <Copy the schematic into your engineering notebook.> that should trigger/cast Effect #0 on player: https://www.wow-freakz.com/spells.php?spell=22864&&name=field-repair-bot-74a (for the player to learn how to craft https://www.wow-freakz.com/spells.php?spell=22704&&name=field-repair-bot-74a)
