Attempted two world bosses today… Claw of Jormag for the daily achievement, Karka Queen for the Mistward Warboots achievement.
Claw of Jormag, client crashed in the middle of combat, without warning during the encounter. No achievement credit, no rewards.
Karka Queen crashed the moment I first attempted to use a skill against her. No achievement credit, no rewards.
Very frustrating. Will be attempting others today. If this happens again, I expect I will simply take several days or a week off, to give Anet time to get their act together and offer a stable play experience.
In the meantime, I will delete my game client and download from scratch, see if that helps.
<GRUMP!!!>
