Aeronautics Delivery Quests

Sky-island quest generation

• Added opt-in skyIslandMode support for RANDOM delivery routes in sparse floating-island worlds.
• Sky-island searches sample multiple landing positions per chunk and stop as soon as safe pickup and delivery points are found.
• Searches load only one candidate chunk at a time and use the configurable randomSearchAttempts limit (default: 96) to avoid world lag.

Enable it in the server config:

questLocationMode = "RANDOM"
skyIslandMode = true
randomSearchAttempts = 96

Safer delivery locations

• Quests now reject water, waterlogged blocks, void gaps, leaves, and unsafe landing footprints in RANDOM, village, structure, and custom-coordinate modes.
• RANDOM generation retries invalid terrain instead of immediately failing the whole quest.
• Cargo placement no longer falls back to seabeds or unsupported positions when no dry landing area exists.
• Search logs now report progress and clearly explain when the configured attempt limit is exhausted.
