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

Check Engine 0.22.0

New: Go back to when it worked
- One button puts your modpack back to the last launch that worked: new mods off, old versions and removed mods back.
- Pick "Mods only" to keep your config edits, or "Mods and configs".
- Nothing is deleted. "Put it back" undoes it.

New: Pit Stop
- A small button on the title screen shows your start time, with ↑ when it's slower than usual.
- Click it: your last launches, every mod, warnings and your last crash in one place.

Fixed
- The crash screen's undo button now finds what to undo.
- Long notices no longer get cut off.
