Guild Wars 2

So I have this permanent bank access contract and when I right click on it I don’t see the option to sell it.
So, is this a bug or you just can’t sell them anymore?

In the last part of Entanglement when I try to save Taimi from Omaad’s device the game just freezes but I can still hear sound; only lightning sparks though. This has occurred three times in a row now.

I’m probably not the only one who thinks this; but it would be a wonderful improvement that when you unlock a certain dye it is unlocked for all your characters.
