Unable to do Battle Of Broken Shore quest

The exclamation point shows on my world map, but not my mini map. There is no object or NPC for me to pick up the quest from. I got all the buffs, turned the quest in, but did not pick up Battle of Broken Shore (thinking I could come back later to do it).
I have completed the Battle For Azeroth quests, reset my UI, renames the folders under retail…my in-game ticket was closed saying I should report a bug.
I reported the bug but how can I do the Legion quests when I’m stuck like this?

Note that the character is a level 110 druid on Icecrown - forgot to change my profile here before posting.

I am posting how I was able to do the quests in case anyone else is looking for help…I ended up having to group with a friend and syncing quests for the NPC to finally show up.

If your meaning to access the Broken shore, you need to make sure you have picked up Uniting the Isles from Khadgar, once you have that you should be able to go to Krasus Landing and get a quest from him called Armies of Legionfall which should let you do the scenerio to unlock the Broken Shore (if you have completed it previously you can also tell him youve heard this tale before and skip). I am not sure given your post what you mean by picking up all the buffs though.

The same issue here, on mini map it show quest “The Battle for Broken shore” but when I go there, the NPC “Knight Dameron” is missing and I can not take this quest.
Does anyone know how to fix it ?
