Neve's barrier not displaying during Fire & Ice

During Fire and Ice, after the dragons are defeated and Ghilan'nain is wounded, Elgar'nan appears and casts an area effect spell. Neve uses a barrier to shield herself and Rook. Before patch 4, the barrier was visible; since patch 4, the barrier visual effect isn't visible. I've seen some other comments about this around social media, so this doesn't seem to be specific to my game.
