NOW COMPATABLE WITH EPIC FIGHT :D

What the mod is:

compatibility & cleanup mod for Minecraft Forge 1.20.1 that prevents and repairs:

  • Hardcore Revival “downed player” clones
  • Corpse / gravestone mod interactions
  • Curios / cosmetic armor inventory duplication
  • player‑clone memory leaks
  • old worlds already affected by clone loops

It acts like a garbage collector for broken player copies, keeping servers stable and stopping ATL (AllTheLeaks)‑style leak spam.

What problem it solves:

Some modpacks that include:

  • Hardcore Revival
  • Corpse / gravestones
  • Curios API
  • Cosmetic Armor Reworked

can end up creating extra hidden player entities (“clones”) during death/revival flows.
Those clones sometimes:

  • stay loaded in the world
  • keep capabilities attached
  • are tracked in memory forever
  • cause memory leaks / performance drops
  • confuse grave/totem/revival logic

This mod detects and removes those lingering clones safely.

How it works:

Prevents new clone leaks

It watches key Forge events:

  • entity joining world
  • player cloning
  • player logout
  • server ticking

and when a revival clone is detected, it:

  • marks it with internal tags
  • blocks duplicate capability attachment
  • discards abandoned clones
  • cleans tracking on respawn or logout

This stops new memory leaks forming.

We will also work on porting to other versions if requested

    This mod extends atl outputs, recognises leak trends, and then recommends fixes based of confidence levels after leveraging spark data. CTL doesn't hide real problems - it filters startup noise and false positives so you can focus on real leaks.
