Small compatibility hotfix for Slimefun Legacy.

Fixed

• Fixed FN Amplification multiblock crafting being detected by other Slimefun multiblocks at the same time.
• Prevented machines from accidentally registering/crafting as unrelated structures such as the Enhanced Crafting Table / Assembly Station or Grind Stone.
• Improved multiblock validation so FN Amplification recipes only trigger for the intended machine structure.
• Reduced the chance of duplicate block registration when multiple Slimefun multiblocks overlap.
• Improved compatibility with Slimefun Legacy 4.1.x and modern Paper builds.

Recommended

Server owners using FN Amplification with Slimefun Legacy should update to this build, especially if players have reported machines crafting incorrectly or becoming registered as another multiblock.

No configuration changes are required — simply replace the existing Slimefun Legacy Jar and leaving current FN Amplification JAR in place and restart the server.
