after the recent update.. Wraith King reincarnation and Aegis of Immortal is not working properly.. when Wraith king dies with his reincarnation available.. he will not respawn immediately.. he will stay where he dies and can't be attacked.. and needs to wait for the respawn timer.. after the respawn time is over.. he will respawn not at the fountain.. but at the same spot he dies.. this apply as well to Aegis of Immortal..
