Crackt

Fixed

• Cracking clusters now match the ore they came from. Every cluster inherited iron ore's mining requirements, so an ore you could already mine could produce a cluster your pickaxe was not good enough to break — mining coal with a wooden pickaxe stalled the moment the first block cracked. Clusters now break at exactly the speed of the ore they are standing in for, including deepslate variants and modded ores.
• Under-tier pickaxes no longer collect ore they cannot harvest. Cracking a vein skipped the usual tool-tier check, so a pickaxe too weak to harvest an ore could still collect the whole vein through its cluster. Ore your pickaxe cannot harvest now breaks exactly as it does in vanilla: no cluster, no drops.
