Guild Wars 2

I’ve been having trouble with my Baby’s First Super Adventure achievement, which requires 27 feats to be completed. However, on two different character I have succesfully concluded World 1, all the zones within and even defeated the queen bee side-bosses. Yet for some reason, I am still stuck on 3/27 feats, with no way to know what the other feats are. As an achievement-completionist, I would very much like this to be fixed, so that I can work towards my living world rewards.

I was guesting on the Aurora Glade server with my warrior, yet as I tried to log back into my homeworld Vabbi with my guardian, I got thrown out of the game and now I am unable to log back in.

The issues it gives are:
The server was unable to authenticate your gameplay privileges. (21:6:3:2205)
The client is unable to gain access to the log-in server at this time. (42:0:9001:4131)

I hope this will be dealt with swiftly.

Completed the event in Timberline Falls, tried to teleport to Lion’s Arch, got kicked out of the game and now I can’t log back in.
