Given that the last fairy with a stick up her ass cursed a *baby* to die and by proxy bring eventual ruination to two kingdoms trying to unite--not to mention the literally draconic reaction she had when Price Phil started fucking up her plans, I'd say Prince Adam/Beast just got the usual dose of pissed off ethereal magic. Sure he wasn't going to die, but threat of a a perma-curse to not only him but his entire retinue is pretty typically thorough for the fae.
Though really, the fairy in BatB seems just plain spiteful. If she really wanted to teach him a lesson, unless she doesn't understand how time passes for mortals, she'd have done something in the subsequent decade to move things along. Orchestrated something that would allow him to see the error of his ways. But Beast just got crazy stupid lucky to actually find love/worked out the curse and broke it at the literal last minute
Kinda makes me wonder how she'd react if she strolled back this way after the movie and saw the outcome...
