Describe the issue (IMPORTANT)

when you press shift and right mouse button, diamond items go into the slot for the ingot, and the ingot into the slot for the item

"ghost items":

Anvil has the same problem, this should still be a vanilla error

I can't reproduce the ghost items issue. Another mod may be causing that one, can you tell me if you still get it in vanilla+Et Futurum Requiem?

Anvil error in vanilla (The Et Futurum Requiem is not installed)

I am aware of the shift click issue, I am talking about the ghost items issue.

Short Question, is a dedicated Server involved? Ghost Items tend to happen when the Server does a GUI thing but the Client does not.

I tried it on a server and I still could not reproduce the ghost items issue.

The ghost items are possibly caused by another mod. Are you able to reproduce the issue with just vanilla and Et Futurum Requiem?

(sorry for the long answer)
yes, you're right, the "ghost items" bug is due by CoFHCore
