I recently discovered that I need the Heart of Thorns expansion to use the glider, so I wish to purchase the expansions available.
Upon trying to do so in steam it tells me I already have them, so does not let me purchase them. I do not remember buying them, but I guess it's possible? - (see screenshot - https://gyazo.com/6dec75cc0755d5a64ec4003a525b8f30 )
I logged into my account on the guild wars forum, and it does appear I already own them? (see screenshot - https://gyazo.com/ac649f63ca2e682ab2cdf05a9bb28ee3)
But they are still not available in the masteries menu, in game (see screenshot - https://gyazo.com/6f0551355d953033d40e15bdb2e53ce5)
Have I missed something? hoping someone can explain what I'm missing.
Cheers.
