I have had an Unhandled exception the last two times I have run SGP, one resulting in a pier crash. The first was with 18.104.22.16869 and resulted in the pier crash. I didn’t report it because the meridian flip error was my own fault (I pushed the wrong button on the keypad of my Mach1GTO after resetting to daylight saving and exited out without saving the changes) which caused SGP to attempt a pier flip before the mount crossed the meridian. However, I expect in this situation that SGP will save me from my own incompetence and park the mount. It did not, I’m pretty sure because I had an Unhandled exception:
Microsoft .NET Framework

I’m pretty sure now that the Unhandled exception prevented SGP from running the park script and I woke up to a pier crash and stalled motors. Logfile is here:
Last night I had the same Unhandled exception, this time with 22.214.171.12473, but it occurred later in the sequence when I was running dark frames, so the mount was already parked. No damage from this one, but I was unable to gracefully exit from SGP in the morning - had to use Task Manager to close the application.
This could be a corrupted or out-of-date MoonLite driver I suppose, but I’ve posted the logfiles in case this is SGP-related. Regardless, however, one would hope than an Unhandled exception wouldn’t prevent SGP from running safety protocols that would park the mount instead of allowing a pier crash.
I appreciate your help and advice!
