Build Your Own Backbone Achievement

[LadyHawk.5319]

I noticed there is now a "Build Your Own Backbone" achieve when you craft the Advanced Spinal Blades. I already crafted the Spinal Blade Pack some time ago, but I didn't receive credit for the new achieve. Anet, can you fix this, please?

I joined the game right after the original LW1 content was removed. That made the only source of the (700!) blade shards my home sprocket node. Do you know how long I waited to craft that thing? It took forever. And now you want me to farm shards, not to mention the rest of the cost, so I can recraft it a second time for 5AP. That's crazy. I assume this was an oversight. Could someone please look into giving us credit if we already have the skins unlocked? Thanks.
