ToME: the Tales of Maj'Eyal

Hello. I am just curious, I previously donated to the game a while ago (ie, I got the explorer difficulty or whatever.) However, I do not have the Stone Warden class - but I do have the custom tiles and all that. So I am just wondering if the class is only for "new" donators or if I should have it, too. Thanks!

Edit: Should point out that I have the addon, and it is activated, but I still don't see the class in the list anywhere.

If it lists as active it should work when you are logged in; to see the class select the dwarf race
