NPC stuck in hospital profession

Anyone else having problems with the Radiology room in the hospital? I’ve upgraded it so that it now takes 43 minutes to complete a task inside this room; however, often my Sim cannot get to where she needs to be because the computer generated Sim is in her way. So those little blue footprints appear, the task shuts itself down, and I have to start all over. This just happened right after the exclamation point appeared indicating the task was complete, but instead, the blue footprints then came up, and the entire 43 minutes was wasted. Second time today. My Sim needs to collect 10,000 simoleans in order to move up a level and wasting so much time redoing this task is making it impossible. Suggestions? Comments? I’ve already complained to IT within the game, but so far no joy.
