Out of the blue I noticed a large chunk of my karma missing (~135,000). I noticed this after I downloaded a patch. I was with my guild capping Glorious Victory WP in Straits of devastation because I had enough karma to get the pieces of exotic karma armor I wanted but the game required an update. After the patch I happened to look at my currency and its now at 18,000 karma.
This happening really takes my drive away from playing. I have not been on for a good month after leaving a prior message to the GW2 team. They never got back to me…
