It is really strange because in the past Ghost update usually means PPR comes after. My case is quite strange. My BC status was "We're processing your background check" since AOR, even before MEP. BC status has never ever changed till now, but I had two consecutive Ghost updates on Nov. 29th and 30th. However, I received no email notification about those updates... Not sure if my application has been approved.. no ADR either. As far as I know, most other people applied from China in August through FSW also have not received PPR, and most of them changed to IP2 in late November..
