SimFactory is supposed to recover from this situation gracefully. However, I have in the past seen it notice that there are no checkpoint files in the last restart, and then start again from the initial data.  Perhaps somebody forgot to write a test case for this situation.  This is not a problem if you use a checkpoint directory shared between restarts (i.e. "../checkpoints").  If you are not using a shared checkpoint directory, I recommend deleting the output-NNNN and output-NNNN-active directories/links for the failed restarts.
