During the daily veteran pledge in final grotto during the encounter with gameyne Bandu boss you are unable to hit the boss with aoe spells or single target spells. We have had this issues in 2 different runs of the dungeons.

First time I had calorops in the floor which we thought was the issues. After wiping several times we reset the instance and still have the same problem with no caltrops being used.

On the ps4 eu if that helps..
