How do you unlock the 4th world in Plants vs. Zombies 2 ??? I've got all 72 stars from the previous 3 worlds, but I can't seem to enter the 4th world.
I think I was given a chance to enter the 4th world once, but there was a warning that having more stars would be helpful. I think I decided to earn more stars. But now I can't find anyway to enter the 4th world.
There's a star portal in the 3rd world. And when I click on that star it just goes back to the time-space taco map (shown below).
I'm wondering if this is a bug in the game. Or perhaps, they'll update the app in the future with access to the 4th world.
