12.1 is the Long Term Support (LTS) code for F5. I would recommend using it if possible as this can be a bug. However, I haven't looked at your iRule and could be wrong. Were you able to diff the configuration before and after the code upgrade ? If there is no difference, definitely move to 12.1 before troubleshooting further.
