I just noticed that keys now have cash (currant) value at vendors. In the past, you couldn't sell keys at vendors, only through auctions.
At a tool vendor, all keys now have a resale value of 40 currants.
At all other vendors, all keys now have a resale value of 35 currants.
Furthermore, all keys can be donated, generating 5 favor.
Anybody noticed when the change occurred?
