This error has been popping up every time I've tried to move points around, whether that's making bank transactions (both depositing and withdrawing) or sending someone points. The points still appear to go where they need to go, so I haven't really paid too much mind to it, but I figure with the Halloween event coming up there'll be a big influx of point transfers happening so I wanted to bring attention to it before then. I use Google Chrome, haven't tried this on other browsers.
