So, I received an authentic Castle rda in the mail, not 3 days ago from Mr.eliquid. Ive had a simple build on it, up until last night when I decided to try something new. I wrap my coil, start tightening my leads and suddenly the top of the screw on the center post breaks off... Is there ANYWAY possible for me to get the screw out? Its all the way in, and fairly tight. Ive looked for replacement posts but have only found one site that sells them and theyre sold out.
