Fusion Reactor Fixer

Prerequisites

Install Java 19 or later. Make sure you check the option to include in the PATH variable.

Verify if it worked: java -version

Download

Download the fusionreactorfix.bat and FusionReactorFix.java files from this gist into the game's save folder:

%USERPROFILE%\AppData\LocalLow\MijuGames\Planet Crafter

Usage

Make note the filename you want to fix, for example, Standard-1.json

Open a command line:

Win+R, type in cmd.exe, press enter.

Switch to the game's save directory:

cd %USERPROFILE%\AppData\LocalLow\MijuGames\Planet Crafter

Type in this and press enter:

fusionreactorfix.bat Standard-1.json

You should see the repair results and a new file with the _fixed postfix, for example, Standard-1.json_fixed.

Rename/overwrite this fixed file back to the original filename.

fusionreactorfix.bat
