When using the autocrafting bit in the extension and you put in a iron block or a block that outputs 9 items even if another iron block goes in it can still output iron ingots.

Closing this given it's in the wrong repo, feel free to reopen it in the correct one if you think it's an issue.

Seems like it may be because you are taking too long to lock the hopper above, try reducing the delay.

Doesn't seem like an issue to me, items are intended to be allowed in while others are in the inventory.

And in case this was an issue this should probably have been reported in gnembon/carpet-autoCraftingTable.
