Looking through the logs on my personal server, I can see a couple FileNotFoundExceptions regarding ic_machine. Here is a list of the classpath strings

• projectred-fabrication:models/item/ic_machine.json
• projectred-fabrication:blockstates/ic_machine.json

This is because we don't use the standard minecraft JSON-based models for our blocks. Instead, we load them up as we did in previous versions of MC. This doesn't effect anything so its not really a big deal.

Maybe @covers1624 knows how to suppress these model warnings?
