My Vampire sim has started a career as a Painter. Initially I did the daily task on the easel, without having any problems. Then I purchased the Digitalistic Sketchpad and tried to use it to complete the task, but even after numerous attempts, it never even started.
The completed paintings show up correctly in the Sim's inventory, but have no relevance to the daily assignment.
