All the worlds were frozen, because Alice went into the asylum shortly after she came back from Wonderland, and was there when Will left Storybrooke. Unless she has magic moisturizer, she was frozen in time for 30 years.

The Curse did three things. Abduct a massive chunk of people from the immediate area of the Curse. Allow you to grab anyone you want, no matter what world they're in (thus why she had to kill Cora. She would've subconsciously brought her along because she loved her.) And freeze all worlds that weren't directly affected by the Curse itself. That's why the Enchanted Forest froze until Emma came to Storybrooke. Not because Cora froze it but because the Curse did.
