Hydrofarm

Added

• XP Drain — drain from more places. A sneaking survival player now drains XP by standing on or beside a floor drain (previously only directly on top), and by standing against or beside a wall/side-mounted drain — for example one stuck on the side of a tank. Ceiling-mounted drains remain right-click-only.

Changed

• Monster Repulser vertical range doubled — ±8 → ±16 blocks (a 33-block-tall field), so it suppresses hostile spawns well into caves and mineshafts below, not just the surface layer. The item tooltip now states the vertical reach.

Performance

• Farmland decay no longer scans a 162-block area on every farmland random-tick for all farmland in the world. Sprinklers now keep a lightweight position index, so farms far from any sprinkler (including vanilla ones) pay essentially nothing.
• Sprinklers and Hydroelectric Generators stop endlessly re-probing their neighbours for water when none is connected — they back off and retry instead of scanning every cycle.
• Butcher Beds no longer allocate a small map every tick while stocked.
