Placed a book in the book printing spot and it crashed with an exit code 0
tested with 10x10x2 of dirt schematic and it worked fine
which makes me think its the schematic that I have that is the issue
The mods that are used in the schematic are as follows:
Iron Furnaces [FORGE]
Refined Pipes
Corail Recycler

Dug through the debug log and found this...

I have the same issue.

The issue is being caused by an unchecked cast in Refined Pipes, not sure if it can be fixed on our end so you should probably open an issue with them
