Woke up to 3 hour gap in imaging, logs

Last night I resumed imaging a sequence that I had used the past two nights. I watched a couple images come in then went to bed. In the morning I saw that only 3 images were captureed

IC1396b - Elephants Trunk_900sec_1x1_HA_0026 - 11:37 PM
IC1396b - Elephants Trunk_900sec_1x1_HA_0027 - 11:53 PM
IC1396b - Elephants Trunk_900sec_1x1_HA_0028 - 12:08 AM

The sequence is configured to stop at 3:30 AM. There is a gap in the logs between 12:08:57 AM and 3:33:28 AM. I woke up at around 3:30 and powered everything down, and did this before disconnecting devices in SGP so errors in the logs around 3:33 are likely a result of that. But I’m at a loss as to why no imaging happened between 12:08 and 3:30. SGP version 2.5.0.23
