I've been using your pipes in the Attack of the B-Team modpack.

I ran across this issue in multiplay while testing out the crafting pipes that crashed the server.
Here is the log from the server crash.

What I was attempting to do was configure a Pulverizer from TE configured to make sand as needed.
I had the extractor pipe configured to one input an extracter chip in an interface for the secondary output and a crafting pipe on the main output.

The server would instantly crash when I tried to input the cobblestone and sand into the crafting pipe.

As of commit 607d45f GhostContainer2 no longer explicitly imports org.lwjgl.input.Mouse. I would guess therefore this will be fixed in next release?

Fixed.
