Guild Wars 2

I’m trying to purchase a character slot with some gems I bought with in game gold a while back, but I am unable I complete the purchase. Once I click onto the button to buy the slot it asks me to click again to confirm, but nothing then happens. This has been happening since earlier today, and I have the same problem trying to buy the free wizard’s hat. It might be unrelated, but I am also unable to see how many gems I have through the Black Lion screen (it shows no number at all in the top left corner) and can only see it in the inventory screen. Anyone else having these problems?

Just to note that logging out an relogging in a couple of times seems to have fixed the problem for now.
