A common issue since a while now, when trying to do the metal press for immersive engineering it will cause the piston to rotate instead of make the actual multiblock structure when having Create: Dreams n' Desires (DnD) and Immersive Engineering (IE) together so this is meant to fix it till one of the mod developers fix it themselves, this can be run through either Client & Server or just Server.
Client side:
Adds a keybind to switch from create and immersive engineering mode
Server:
Just shift+right-click the air to switch through modes and will show an action bar saying it changed.
