2 problems found. Syncing scheduled threads was not happening at all because the job was not being rescheduled. Did not want to deal with changing job call times so I called the new scheuduled_thread_sync routine from advance_sim_time. That's where it started, it'll be fine. Also found that I was resetting job complete flags too aggressively. The check to test if the thread is ready to run was missing. Added that check back in.
