Spells and Spellcrafting 2.12.79 — release notes

Fixed

• Devourer workers no longer fall out of the world. A worker sent to dig near a ravine, a cave mouth, or any open drop could end up stranded in mid-air, and when the job finished it fell into the void — taking the tier you had fed it with it. This was permanent and unrecoverable, and it happened in ordinary terrain.
• Workers recovering from that hazard now land somewhere they can actually stand. An earlier attempt at the fix could park a worker inside solid rock, and a later one could aim it at a spot that was only planned to be filled rather than filled yet. Recovery now checks the ground that really exists at that moment, and falls back through the work area and then to you if it has to.

Under the hood

• Minion tracker updates are no longer sent to connections that cannot receive them. Players are unaffected — a real client always negotiates the channel before it can join — but the unguarded send crashed automated test runs in packs where several mods are installed together, and it would have become player-visible if the mod were ever made optional on the client.
• New automated tests covering both fixes above, each including a deliberate check that the test can still fail if its fix is removed.

Requires / compatible with

• Minecraft 1.21.1
• NeoForge 21.1.224+
• Optional: Zombie Village, Lootr, Curios
