Fairly recently, I ran out of skills to learn, and am also getting low on quests. so I decided to focus on my long neglected cooking quests and was diligently working on frying, chopping, grilling and making stuff in my awesome pot.
I must have made 100 sauces in last week's test in an attempt to get the recipe for bolognese for the awesome pot quest. Out of no where, yesterday, a last skill popped up for me to learn: Saucery 2. Once I chose that skill, duh, I got a quest that included bolognese sauce. But that was a several days after I had supposedly exhausted my skills list.
Not sure if that is a bug, or the result of a helpful genie who overheard me whinging about it in chat, but thought I would mention it...
