Describe the bug
During the loading of minecraft the game crashes whilst attempting to load Immersive Intelligence version 0.2.1. At first, I had other mods installed too however I removed them, and the same issue occurred.

To Reproduce

1. Launch game (1.12.2-forge- 14.23.5.2855) with Immersive intelligence and immersive engineering (0.12-98)
2. wait while game loads
3. On step 2/7 during loading the game crashes

Expected behavior
Game loads and I play Minecraft

Environment

• OS: Windows 10
• Minecraft version: 1.12.2
• Forge version:
• Immersive Intelligence version: 0.2.1
• Immersive Engineering version: 0.12-98

This is a known issue caused by loading a pre-0.2.1 config file (motor belts had major changes).
Please remove the II config file from [main folder]/config/immersiveintelligence.cfg.
A new config file will be generated; if you made any changes to the old one, make sure to move them.

Oh thank you so much
