Sync Fix Mod (1.20.1, 1.20) designed to stabilize vanilla server ticks and reduce tick‑driven desync without altering gameplay mechanics. It directly addresses one of the most common causes of lag and “desync feeling” in modded worlds: server tick overload. By keeping the tick loop stable under pressure, SyncFix ensures smoother block updates, scheduled ticks, and world logic.

Features:

  • Prevents spiraling into multi‑second tick debt when the server falls behind.
  • Monitors real server tick time with minimal overhead.
  • Differentiates between sustained overload and short spikes, no hard tuning required.
  • Adjusts vanilla scheduled tick processing during overload, then relaxes back to normal once stable.
  • Does not change semantics or mechanics, only improves stability.
  • Designed for real server environments, especially modded worlds prone to tick stress.
