When trying to input enriched iron into a metallurgic infuser with carbon in it. It refuses to accept the item and puts it back into player's inventory.

Here to give this a +1. Enriched iron is pushed straight back to player inventory.

I have this issue too. It happens with or without carbon. Enriched iron doesn't go in, nor can it be piped in.

I'm also encountering this issue in my ATM9 world. Alloying iron in any version of an infuser simply stopped working. Items will go in, but nothing is made. In addition, my PRC stopped functioning while making plutonium. This happened after I logged out and came back to it. Machine that had previously been working simply stopped accepting inputs. Fluorite dust gets kicked back to user inventory.

This issue is fixed for me in version 0.2.32.

@aobrem Our server patched up to .32 and my machines started working as well. No specific fix mentioned in patch notes, so we'll see if they stay fixed.

I have the same problem on modpack version 0.2.34, the metallurgic infuser won't accept the Enriched Iron.

1.20.1 - 0.2.34
The Metallurgic Infuser refuses Infused Alloy with Diamonds as extra, to craft Reinforced Alloy.
When inserting the Infused Alloy per cursor action, it places the Infused Alloy in the machine and immediately back to the curser.
When inserting the Infused Alloy per shift + left click, it puts the Infused Alloy in the correct slot in the Metallurgic Infuser and then immediately puts it back into the inventory.
Piping the Infused Alloy into the machine didn't work either.

Reloading (/reload) crashed the server, everything worked as intended afterwards.

I have the same problem on modpack version 0.2.34, the metallurgic infuser won't accept the Enriched Iron.

I have since restarted the server, and it works again.
