Leaky is a mod to detect, report and remove large amounts of stacked items, and improving the performance of items in general.

  • Configure Item performance improvements
  • Configure chat notifications
  • Configure item glowing
  • Configure reporting intervals
  • Configure min amount of items stacked to report
  • Configure amount of items stacked at which those items get auto removed

No known incompatibilities, should work with any other mods.

Only required on serverside
