I got this idea a couple days ago.
There should be a command word to allow you to get your gem back while crafting...lemme explain
Lets say, you're crafting a durby, and you lag out or go away for a moment, and someone starts crafting your rock for ya, taking ownership for it. Well, what happens if you want the rock back but they wont stop hitting it, stealing your rock? Well, with what I'm thinking, the original owner should be able to say a word or something, to regain ownership of the rock. I thought of this when I lagged out, and someone (2 peeps, actually) stole my durby, and wouldnt give it back

I know it woulc bring up problems ("giving" your rock to someone, then taking it back last second) but it would clear up alot more craft stealing than make craft stealing.
Good Idea
Bad Idea
