Upon starting the modpack Enigmatica 2 Expert - Extended, I am getting a crash report from the Launcher saying Minecraft has crashed. Here is the file generated by the game:

1. Is this issue reproducible? If you create new world, is it still crash?
2. Does this happens each world creation?
3. What happen if you join same world again?

Try to update your java. Logs write that you are using 9 years old version.

This happens every time I join the same world. As for new worlds, I get the same crash page.

Try to remove file scripts/mixin/openterraingenerator.zs, restart game and create new OTG world.

I'll give it a shot and let you know if it works. Thank you for the help.

It didn't want to work for me. I even tried updating the launcher to see if that was the problem.

I have updated java, re-installed Minecraft, java, the modpack, and even used the previous version of it. None of it has changed the same error I am getting when I load the save file.

Please send new logs. Java 8_51 is known trouble maker, causing problems before, so i want to be sure your running MC on more fresh version.

Also, you can try to remove file D:\Minecraft\Instances\Enigmatica 2 Expert - Extended\saves\Bold Move\OpenTerrainGenerator\Config.yaml and replace it with this one.
