Matched line in report:
[03] |   |   |   entities(68.4%/58.1%) - 138/138
Troubleshooting steps:
  1. Lower Simulation Distance to 6–8 chunks so distant mobs and farms are not ticked every 50 ms.
  2. Inspect mob farms, villager trading halls, and uncovered hopper chains (place composters on top of hoppers).
  3. Install Lithium (tick logic optimization) and EntityCulling (skips rendering hidden entities).

Where do I find my Minecraft error log?

Open your game profile folder. Copy a file from crash-reports or logs/latest.log. Exit Code 1 alone does not explain the crash.

Where is my log sent?

Analysis runs in your browser. Your log is not uploaded to DEPTANA, stored in settings, or included in a shared URL. The text limit is two million characters.

Does a match prove the cause?

Diagnostics checks known error signatures. A match suggests what to inspect; it does not prove the sole cause. If no rule matches, the tool says so.
