Resources by Biome

Content Expansion 1 is activated on EU #1. It is a guarded content layer over unchanged Worldgen V4, not another biome or generator profile.

Environment	Expansion sources	Wildlife
Plains	Sparse Wild herbs, small Gravel patches	Wild Rabbit, occasional Deer
Forest	Herbs, fallen logs, mossy stone; tap trees for Tree resin	Forest Deer
Desert	Limestone, sparse Gravel and Quartz; harvest Cactus fruit	Desert Lizard
Swamp	Mud and Peat	Rare Marsh Turtle, shallow-water Marsh Leech
River / Coast	Shallow Seaweed, fishing catches	Wetland fauna only where suitable
Caves	Slate, limited Copper ore and Quartz replace ordinary stone	Cave Bat

New objects never replace precious ore, protected portals, claims, saved edits, buildings or occupied tiles. They are considered only on safe chunk load, not injected into an already visible chunk. Resources regrow after catalog timers (normally 20–30 minutes), with protection/occupancy rechecked. Tree and cactus harvests have a persisted 20-minute cooldown even when the yield roll fails; reconnecting does not bypass it. Hold left-click for nodes; right-click trees/cacti to harvest. Old rare metals and mining progression remain unchanged.
