If you're adding slices to a Printer project. It is recommended you use the Printer slice command. In any event where you're importing slices from somewhere else. You will need to update the reducers.json file in order for Printer's auto generation code to work properly. The slice command will not include the slice in the reducer imports elsewise.
λ You need to manually update reducers.json if importing a slice
λ Use Printer if possible and then import business logic to the new slice
