When I try to use the Punch Designex it's results don't stick. When I try to combine two items it finishes and then the resulting punched card disappears and the items return to the input slots. When I try and punch a single item the resulting card goes back to being empty and the item is lost.

Any idea what could cause this?

Additional information, it appears to be some sort of server issue as I do not have this problem in singleplayer that I can determine.

Ah! It appears to be a result of turning the hard Designex mode on in the config. Problem half solved, at least my server will work now.

Okay, I'm going to start working on it immediately.
