What do the numbers next to the recipes in the crafting window mean?

In my crafting window there are numbers next to all the items I can make, but I don't know what they mean. I initially thought it was how many I could make with stuff I had on hand, but in my screenshot I can clearly make 3 when it says 0. Is it bugged or does it mean something else entirely?

Those figures are supposed to show how many of the item you can make, I believe the fault you have pointed out is because of the systems inability to differentiate between your characters inventory, and yoru cargo hold inventory :S

Additionally the intensity of the colour indicates how much of a boost the item will give the crafting skill when made:

• grey ( + 0 pt )
• green ( + 1 pt per 2 items made )
• yellow ( + 1 pt per item made )
• orange ( +2 pt pre item made ) ~VMT to sarge-smith, and mufasa for this information~

It might be worth popping into the devtracker forum and letting them know about this.

They're supposed to represent how many you can craft.

But, as you've noted, the crafting UI is just a little bit broken.
