Environmental Core

Environmental Core for Minecraft 1.21.1, the same as 3.2.1 for 1.20.1.

Requires NeoForge 21.1 (any build) and ValkyrieLib 3.2.1 or a newer 3.x. Worlds from 1.20.1 carry over.

Fixes

• The Interdimensional Modifier made an Amplification Modifier's machine part, which 1.21 refuses: placing one would have stopped the game. It has its own now, and one placed in an older world keeps its values.

Changes

• Shared tags follow 1.21's conventions: c: where they were forge: (c:gems/litherite, c:storage_blocks/mica), with 1.21's new names for some (c:stones, c:glass_blocks, c:cobblestones).
• The Piezo Modifier's Assembler recipe takes quartz blocks as before, through c:storage_blocks/quartz, which Environmental Core fills, as 1.21's common tags dropped it.
• Datapacks: data folders are singular from 1.21 (recipe/, loot_table/, tags/item/), so this mod's machine data is in data/<namespace>/recipe/, and a recipe's conditions are NeoForge's, "neoforge:conditions" with neoforge:item_exists, neoforge:mod_loaded and so on.
