Pack Version:
Some version not long before 05661d4, I'm not quite sure.

Description:
The Automation Interface (henceforth, "AI") lets you dupe items, and combined with Little Tiles' dupe bugs, allows you to beat the pack in <30 hours.

Expected Behavior:
The AI should not be usable for item duping.

Steps To Reproduce:

1. Put a GT input bus above an AI.
2. Set the AI to "Auto Insert" from the side "UP".
3. Put any item into a the Extended Crafting table below the AI.
4. Press "Save Recipe" in the AI's GUI.
5. Put the item, or another one of the same, from the crafting table into the input bus.
6. Extract duplicated items from the crafting table.
7. ???
8. Craft the Creative Vending Upgrade in <30 hours.

Screenshots:

Jokes aside, we know that Automation Interfaces have a glaring dupe bug. We guide players away from using them because they're so error-prone. The problem is with the mod they come from.

Here's the problem: BlakeBr0/ExtendedCrafting#99

So I don't think we have any hope of them fixing their broken mod.

Of course. However, as previously discussed, another ingredient could be used in its place. I made sure to word the actual content of the bug report very carefully with "The AI should not be usable for item duping."

The littletiles dupe bug is already fixed in an update that is part of PR #476.

Unless EC elect to fix the mod itself, all we can really do is deprecate the AI and put in a non-functional placeholder to band-aid the issue while keeping crafting recipes / balance mostly unaffected.
