A Reflection of Truth quest help

Hi. This takes place in Ravendreth with The Accuser questline. I went through the mirror and was in the middle of protecting The Accuser when I got disconnected and now everything is just gone. I can’t get back to the quest. There is nothing to abandon and restart. The Accuser is no where to be found. I reset instances and still cannot get back on that quest which leaves me unable to continue with the Ravendreth campaign. If anyone has encountered this and knows of a solution, please let me know. I submitted a ticket, but there is no telling when someone might get this fixed. Thanks.
