Bugs With Hospital Profession.

I keep experiencing a bug in the hospital. My nurse sim goes to do things with the X ray machine and for some reason when I go back she’s stopped and I have to start it all over. Occasionally I catch it when it happens and there’s the footprints icon comes up indicating they can’t get around something and have to start it over again. 

Anyone else experiencing this? 

I hope this can be fixed because it’s super annoying and wastes time
