I had a long schedule last night. A few jobs went through happily. Next job started, focused, aligned, switched filter wheel and sat idle. See around 00:47:50 in the log. At 00:51 I noticed that and hit the stop button in the Capture module (not the Scheduler). It cranked through its error handling and successfully restarted and kept working fine through the rest of the night.
This is not a new error. I saw it multiple times over last couple years. Sometimes, like this night, I see the sequence in Capture correct, just not running. Sometimes the sequence is empty, like not loaded from specified file.

Thank you for the report, we will investigate this.
