Last night twords the end of the fight with Jormag I took a screen shot to report a person for flying in the air who was also attacking Jormag. The problem was that as soon as I pressed the screen shot key the game locked up. After a few seconds the music changed (which indicated the battle had ended) but nothing on the screen changed. I ended up using task manager to close down the game and I then relaunched it and was able to collect my reward from the chest. The event rewards (a few silver, karma ect) were not awarded.
Once again, during the fight with Jormag, my X-FI Xtrem Gamer was over loaded to the point that most sounds were not playing. For most of the fight the only sound working properly was the background music.
I am not going to attach the screen shot because it includes dozens of charactor names.
