NOW COMPATABLE WITH EPIC FIGHT :D
What the mod is:
A 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
