The above quote seems to be the "cause" of the bug. Should be pretty obvious from that quote that we, handcrafters, are not only filthy but cheaters too. >_>Surplus items from crafting are again available for crafting other items. For example, crafting two green circuits will no longer result in two extra copper wires in the player's inventory. This only applies to items that are automatically crafted as a prerequisite; items the player has explicitly requested to craft will not be used to satisfy the dependencies of any further orders.
I'm not sure what the rules are on posting item dupe methods. So I'm going to PM Kovarex and Rseding91 the instructions. I'm making this post so that everyone knows there is a working dupe method in 0.13.14 and 0.13.15, that anyone in the Factorio Staff group can also request the instructions to replicate, and that there is a tracking "ticket" for the issue.
I'll post the reproduction steps once either there is a fixed Factorio released or a Factorio staff gives the ok to post the instructions.
