Yes my work zones are set up properly I have the caretaker and vet assigned to the workzone and yes it also happens every time I start a new gameIll ask a question that might be helpful.
Do you have workzones set up and might it be a case where you dont have the caretaker/vet not assigned to the workzone this building is connected to?
Looks like either that or just a buggy path. Does this also happen in new parks you start?
