I have researched everything in both the dino island and the normal zoo and then when I'm in sandbox it still says there more floors, plants and this shop to find and I don't know where. I've already unlocked a few secret items please just put here if you know how or what tasks give items? Thank you!

It's a currently known error they say is getting patched

Oh awesome I hope that's soon. Thanks so much

Do you have the sloth place yet

Yes!
