Hello, I ran into an issue with Mythic Metals.

Log:
latest.log

Minecraft exits with:
The game crashed whilst initializing game
Error: java.lang.RuntimeException: Could not execute entrypoint stage 'main' due to errors, provided by 'aiotexpanded'!
Exit Code: -1

+1, this mod needs to be updated to support the new MM release

Still appears to be an issue

It appears that the mod developer is no longer active on this project, I will attempt a PR when I can.

Fixed with this build:
https://github.com/CamperSamu/aiotexpanded/releases/tag/1.4-mm-fix

Thanks for thar :)
