I just mentioned steven and i advise others to do so, he needs to fix that before he sends them out, if he fixes that obvious error that'd be perfect.
We've got two threads of people who are directly communicating with Steven and working on those designs.....

@blankrider noticed the issue with that piece immediately and has probably already messaged Steven regarding it.
Lets try not to have too many people directly contacting Steven to make changes to the designs. Too many conflicting messages might scare him off
