Thanks for the update! I'm unfortunately noticing a new bug since updating. I made new work zones, and assigned staff to them accordingly, but now my Keepers won't attend the habitats. I had a notification for hungry flamingos, so I called a keeper to the habitat. The keeper just walked around and said the animal wasn't hungry. This is my first time experiencing this particular bug.
I tried assigning a different keeper, but nothing worked. Going to try deleting all work zones, and removing/replacing the feeding stations to see if it helps.
EDIT: It was the work zones. I deleted them all and the issue went away. Now the issue is that I can't create work zones for each habitat because the keepers can no longer access them once the habitat is in a work zone. Vendors seem to be unaffected.
