I have a simple setup where I have a hopping bonsai tree depositing stuff from an oak tree into a chest, which takes the logs and feeds them into a redstone furnace to make charcoal to power a steam Dynamo.
The thing is, I checked because I started losing power and the furnace was producing Dark Matter from the mod Forbidden & Arcanus.
I don't have anything from that mod, and I checked the recipe and it shouldn't even be producing Dark matter, as it needs edelwood and not oak wood.
I have no idea what to do as I've tried moving the furnace, changing the tree type, replacing the furnace, anything I can really do. I replicated my setup in a vanilla world, and it worked fine, so I'm led to believe it's the server itself.
Any help is greatly appreciated!
Attached here is a pic of my setup:
