Floor Is Lava

• World Generation: Natural Overworld, Nether, and End terrain floors are now converted to static lava blocks with magma underneath, while preserving key structures and resources. Static lava uses much less computational power than regular fluid lava.
• Mechanics & Gravity: Player-placed blocks (excluding obsidian) now follow gravity rules and will melt if placed over static lava. Placeable blocks are limited to just planks, cobblestone, and utility blocks. Planks melt after 10 seconds of being placed on static lava, and cobblestone takes 15 seconds. Other blocks melt instantly.
• Mining & Progression: Mining is restricted to prevent tunneling and lava avoidance. You are permitted to mine player-placed blocks, logs, leaves, planks, stone, and deepslate. Multiple vertical shafts are located at strongholds since mining is restricted.
• Mob Adjustments: Passive animal food drops are tripled (besides fish), and mob spawning rules are updated to favor spawning on trees. Hostile mobs ignore light levels and daylight; they also receive combat upgrades post-Nether. Zombie Piglins have a 1 in 4 chance of becoming a strider when spawned (striders weren't spawning for some reason, so this fixed it). Spiders are always hostile.
• Removed Items: Fire resistance potions
