Guild Wars 2

Over the weekend after the monthly achievements reset a friend and I decided to get the experience achievement out of the way. So Sunday night we did all 100,000 XP. Now when I look at the October achievements where the experience area is, all it says is “???”
This has also happened to my friend as well.

Has this happened to anyone else? Is there a way to fix it?

It is an unknown achievement that will be revealed later on. It has been said in a few topics.

here is the link to a Screenshot were a GM was talking in /m
