Direct answer

Use the crash report to identify the block entity and coordinates, plus the mod/plugin that owns it. Back up first; update/fix the content and recover only the affected block/chunk if necessary rather than deleting the entire world.

What it means

Locate the block entity from the crash report and recover cautiously without deleting the entire world.

Block entity vs. entity

A ticking block entity crash concerns a block-attached object such as a chest, furnace, machine, or other block entity. A ticking entity crash is the separate case for mobs, items, projectiles, and other entities.

If you are a player

  • Note the exact world/dimension, coordinates if known, and action that triggers the problem.
  • If other players can reproduce it in the same place, tell the owner; location-specific evidence is valuable for world/chunk problems.
  • Do not repeatedly force-load a crashing area if the server is unstable. Let the owner make a backup before repair attempts.

If you run the server

  1. Stop the server and make a full backup before deleting, regenerating, downgrading, or editing world/player data.
  2. Use the crash/latest log to identify the specific player, entity/block entity, chunk/region, datapack, registry entry, or mod involved.
  3. Fix/update/restore the content that caused the bad data first; only remove the smallest affected file/entity/chunk when no safer recovery exists.
  4. Test recovery on a copy and verify the server can save/restart cleanly before putting the repaired world back into production.

Important notes

  • Recovery commands/tools differ by server software and whether the server can stay online. Use the crash coordinates/UUID and a backup; do not publish a destructive one-size-fits-all command.
Recover the exact block position safely
  1. Read the crash report for dimension, block-entity type and coordinates. A chest, hopper or machine mod may be the affected block; avoid deleting an entire region without knowing the cause.
  2. Back up the world and test restoring it in an isolated server. Disable or update the responsible mod/plugin only after verifying the saved data format.
  3. If surgical repair is unavoidable, use an offline editor compatible with the world version and confirm adjacent inventories and neighboring chunks survive.
