FATE complete, not marked off in Book

I completed the FATE 'The Taste of Fear' in Coerthas Central Highlands, but it was not marked off as completed in my Atma Weapon book. Considering this is a fate that only spawns once every few hours (and no, grinding the other fates in the area is not an option given how big the zone is and how fast the fate is cleared when it inally comes up) this is a major disruption to my gameplay.

Did you have the right weapon equipped and you need to participate a lot in the fate can't just show up last 15 seconds do two or three attacks to get it checked.

I was there for a good ~80% of the damage, and my Thyrus Atma is always equipped
