So I was in exchange, and I was selling a ship for 894500000 EC. It kept going to 985000000. On my last attempt the screen froze like in the tailor. When I came back on, nothing. No EC, no ship. I got an email after saying I sold it for 8 million I think ( no I didn't make the mistake) has anyone else ever had anything like this happen?
