Guild Wars 2

I have been trying to do this challenge mote since the changes were made to the instance. The problem is when changing from one boss to another someone in the party always seems to disconnect with no way to return. Furthermore, if the instance started is the one forced to disconnect the whole party is kicked out. The change from one boss to another seems to be when people will disconnect or desync. The first boss will usually load fine but switching to the second or third will crash some people back to character select. A fix for this would be much appreciated. As it stands it is hard to get a group to do this since a disconnect is more likely to wipe an organized group than the bosses.

Just got past Eir tonight and was ready for the much easier Canach when the instance owner disconnected forcing the party out. Either a way for people to rejoin and keep their challenge mote achieve or a fix to the disconnects would be greatly appreciated. This achievement has been taunting me for ages.
