Guild Wars 2

I opened the Black Lion Trading Gem Store only to discover 500 GEMS were missing. I had not made any purchases, redeemed any for gold or made any such transactions. But my gems are gone, correction half of my gems are gone. I had a total of 1,000 a few days ago, now I have 500 and as stated I made no purchases with my gems.
My last purchases with gems were for a Bank Tab Expansion and a mini Snow Flurry Dragon, but that was weeks ago (during Wintersday for Bank Tab and prior to or early Wintersday for Mini Snow Flurry Dragon).
I had 1,000 gems in my account on Monday, now only 500. Again I have not made any purchases or redemption of gems.
It takes a lot of time to accumulate that many gems. What a waste if someone can just walk in and steal them.
Please Help?!?!?!?!

The World Summit – Storyline – Network Error Code 1022:5:1:874:101
Bounced out of storyline element to Character Select.

I’m having great difficulty with this story line element. I am receiving this above noted error code and being bounced out to the “Character Select” during the storyline element. I have sent in numerous “Report a Bug” outlining what causes the bug, differences I’ve made, different progressions. It seems to hinge on Health. You are allowed a single death, but if you have a 2nd it gives you the network error. I also encountered a second way to be bounced out: After faltering the first time, before clicking on ‘retry from waypoint’ I opened my inventory and tried to use a repair canister at which point I instantly got bounced out and received the same error code and I’m back at square one. choosing which character I want to play.
HELP!!!
