Spida with Skyscrapers and stuff

v1.6.0 — Crime, Big Cities & Venom Smash

CRIME EVENT SYSTEM
* Robberies now break out at night in cities (where villagers gather) — pillager "robbers" spawn and you must stop them
* Defeating robbers builds Reputation; every 10 points earns a reward

NEW STRUCTURE: BIG CITY
* A metropolis made of 4 cities tiled 2x2 — 336x336 blocks, up to 8 houses and 8-12 iron golems
* Rarer than regular cities; /locate structure spidercity:big_city

VENOM SMASH
* Wearing the full Symbiote set, landing from 8+ blocks triggers a ground-shattering shockwave — 8 damage in an area, +3 per extra 5 blocks fallen, with knockback; you take no fall damage from the smash

WORLDGEN & LOOT
* Skyscrapers now avoid the entire city footprint (no more towers clipping into cities); cities avoid vanilla villages
* City sidewalks now occasionally have loot chests
