So this might be first defect with the new island.
First thing I did when I saw the new island was to create 3 legendary habitats. I ligned them up along the back and right side of island. When I came back to a short while ago, I only see TWO of the habitats and they're now along the front. I cant even find the third island, and I know it has to be somewhere because the worker count says three (i have the premium island active).
