I just wanted to get this of my chest, so i'll post it here..
When I was playing Nightfall yesterday, the last mission area was kinda empty.. After trying with henchies and heroes a few tiems (which Iall failed when I neared the end..) I decided that a human party would be a better option..
So I stood there, for about an hour or so, until I finally managed to gather a party of 5.. we hopped some districts and after about another hour, we had the party we needed to kill abbadon.. (3 warriors, 1 dervish, 2 monks, 1 necro, 1 paragon)
The battle took place, and we were victorious, so far so good

When we got to the last endgame area, we enjoyed the fireworks, listened to the story and some of our team bought armor.. I got my endgame book of secrets (hooray, *cheers*) and after a carefull consideration, I decided to get the forgotten sword for my warrior

When I spoke to the NPC that would take me back to Kamadan, the loading screen started.. And shortly after that, I lost my connection due to an error7.. (my connection was working great by the way..)
I closed the program (what else was there to do?) and restarted guild wars.. after I logged in, I took my dervish to put the sword in storage.. What I then saw stunned me greatly.. My endgame sword had been replaced by ..... " THE BOOK OF SECRETS!!!" So in order to get me my hardearned sword, I had to beat the boss again!! I know this shouldn't take long, but all my effort in getting a capable party and finishing the game were kinda spoiled..
Please A-net, fix these wretched error 7's... They drive me utterly crazy, cause in my case, they only tend to show up at big moments...
