I skated there yesterday with some of you, looks tight. I think I found how to keep the glitch working. Whenever I try to make a new park, it freezes, which might be happening to some of you, but whenever I go into a park already started(with the update) it works, and I can build magic. So just start a park with the update, then go to dashboard, delete cache, start S3, don't accept update and continue your magnificent park.
