v0.8.21 — harvester ping-pong, recall VFX, local bot matches — Soup: the Game Steam update #556210

Harvesters ping off each other. When two collide they bounce, and now there's a sound for it. A swarm of them starts to sound almost musical when they cluster. Recall now has a visual effect. A gravity-lens distortion follows the recall — you can see units being pulled, not just dispatched. Local games with bots. "Play with Bots" from the main menu drops you into a real match. Stability. Various crashes and edge cases fixed. Rust 1.95. Toolchain bump.
