1.5.2 — no more empty batches

Fixed

• Mobs whose loot rolls "0 or 1" (phantom, and any table that only drops when a player lands the kill) could still produce an empty batch. The expected-value fallback now rolls with the killer in the loot context, and if every roll still comes up zero it produces one item from the table instead of nothing.
• Both 1.21.1 and 26.1.2 builds are included.

1.5.1 — sample fix, material cards, second output page

Fixed

• The mob farm accepted only entity cards; spawn eggs, spawner items and modded mob containers work again (a "living entity" check used EntityType#getBaseClass(), which answers Entity.class for every type).
• The Auto Farm opened the mob farm's screen (its menu was registered under the wrong menu type).

Added

• Four random material cards: Ore, Crop, Tree and Plant. Put one in the matching machine and every batch draws a random sample of that category. Cards are not consumed and always produce something (empty draws are re-rolled).
• The Auto Farm and the Auto Ore Farm now have a second output page, so a full output buffer no longer blocks production.

Both 1.21.1 and 26.1.2 builds are attached.

1.5.0 — Fluid Farm & Mob Farm

New machines

• Simple Auto Fluid Farm — 9 independent tanks with their own level bars, auto bucket filling, and the inner block renders the real fluid texture.
• Simple Auto Mob Farm — feed it a spawn egg, a spawner item, a mob jar or any modded mob container; it runs the full death pipeline (affixes, gems, global loot modifiers) and outputs across two pages.

New items

• Entity Card — right-click a mob to bind it, then kill that mob to fill the card (requirement scales with base health, capped at 32 kills). Craft with paper to wipe it.
• Animal / Monster / Boss Entity Card — randomly rolls a mob of that category every batch.

Also

• In-game config screen (NeoForge built-in) with three hot-editable options.
• Machines no longer let pipes pull samples or upgrades out; generators only accept fuel and will not give it back (Pro lava included).

Both 1.21.1 and 26.1.2 builds are attached.
