LagShield v2.1

I reworked the system so it doesn't react as aggressively to lag.

Changes:

  • New Logging: The mod now writes to logs/lagshield.log instead of spamming the server console. It keeps the last 1000 entries for debugging.

  • Less sensitive: Redstone, physics, and explosions are no longer disabled all at once.

    • Physics disables below 14 TPS.

    • Redstone disables below 11 TPS.

  • Mob Spawns: A small amount of mobs (5%) will now allow spawn even during heavy lag, so the world doesn't feel empty.

  • Config: Added new settings for the TPS thresholds.

Note: Please delete your config/lagshield-common.toml to generate the new values.
