Check Engine

Your modpack's check engine light. Crash, missing mod, broken recipe or "Invalid player data" kick? It tells you what broke and how to fix it, in plain English. Undo bad updates, find the faulty mod, back up and rescue your worlds. Never touches gameplay.

What's new

Crash Doctor is now Mechanic, and Strip Mine is now Misfire. They work the same.

New for modpack makers:
- Switch off the parts of Check Engine you don't want.
- mode=modpack: players only see what stops the game, crashes and world backup warnings.
- Check Engine goes quiet where another crash helper mod already shows the logs. The fix buttons stay.
- config/checkengine-pack.example.properties lists every setting.

Fixed: a false "Fixed" message when a modpack hides a warning, Go back undoing a modpack's Check Engine settings, and a wrong memory warning with some launch flags.

This mod has no additional files
