Error registering event handler for multiblock format event

[KylePoe]

Hi all, I got the following error in my forge server install log.

Forge version: forge-1.12.2-14.23.5.2847-universal.jar
Minecraft version: 1.12.2
Context: MC Eternal serverpack 1.3.7.1

Not sure how this will manifest in gameplay, but I will update when I know.

Have you tried Immersive Technology instead of Immersive Tech?
This project is pretty much abandoned.
