Staaaaaaaaaaaack Mod (1.21.8, 1.20.1) – Merge Items Beyond Vanilla Stack Limits in Minecraft

Staaaaaaaaaaaack Mod (1.21.8, 1.20.1) is a lightweight performance-enhancing utility mod designed to optimize how dropped items behave in Minecraft. Instead of allowing hundreds of identical items to clutter the ground and strain your system, this mod intelligently merges them even when they exceed the vanilla stack limit (e.g., 64). This doesn’t affect how inventory stacks work, but it significantly reduces lag, particularly in farms, mob grinders, or mining runs with mass drops.

This mod is perfect for modpacks, performance-focused servers, and players who frequently deal with mass item drops and want a cleaner, faster gameplay experience without compromising vanilla mechanics.

Features:

• Stack Overflow Merging
  Dropped items of the same type will merge beyond their default stack size (e.g., 128 arrows on the ground will become one visual item instead of two stacks of 64).
• Improved Performance
  Reduces lag caused by too many item entities on the ground ideal for farms, mob grinders, or redstone factories.
• Custom Merge Radius
  Define how close items must be to automatically merge, allowing for fine-tuned behavior in dense item-drop areas.
• Customizable Max Stack Size
  While it doesn’t change the actual in-inventory stack limits, you can configure how many items a single ground entity can visually represent.
• Blacklist System
  Prevent specific items from being affected by the overflow stack merging if you want them to behave like vanilla (e.g., armor, enchanted gear, etc.).
• User-Friendly Inventory Management
  Easier to collect and manage large quantities of the same item with fewer dropped entities cluttering the world.
