Guild Wars 2

Hello
Got this problem with Hope vol.2 – I already finished vol.1, got maxed legendary crafting masteries and can’t buy Hope vol. 2. Anyone have any idea why? Thanks for help.

Btw. Added some links to screens:

did you craft the weapon (research)? you can’t buy the next book until you do that

Hmmm … Completely forgot about it O_o
Cheers for quick reply ;]
