Whenever I have a quest for a Ghost King, one I eliminate the archers and the Ghost King is vulnerable again my quest vanishes - if I kill the King I don’t get ‘Quest Completed’. If I hang around for 30 seconds to a minute then the quest reappears and I can happily kill the King and get my ‘Quest Complete’. It means if I am not soloing it, then I don’t get my Quest.
This happens every Ghost King
This only happens for the Ghost King
