Hey, one of my users just reported a strange issue with the Automation Interface - I'll just link to the issue, I hope that's alright:

EnigmaticaModpacks/Enigmatica2Expert#180

Hey, even after replacing the automation interface, putting the recipy in again, etc., it started creating ingots out of thin air again today. I do not know what is triggering it. Again, looking inside the automation interface stopped the process of extra ingots being created. It did seem to use power during the process by the way.

Since I think you said you're playing on a server I have an idea of what the issue could be. Does the issue only happen after a server restart?

Possibly, the server should restart every night, and it does seem to occur only once per day. I just restarted the server manually however, and I have not seen any duplication as of yet. I also started autocrafting the ultimate ingot, so lets see, I'll keep an eye on it.
