I had this happen again, and I noticed that similar conditions occured.
1. The mount was ending an imaging run pointing West at Target Coord (JNow) => RA=08 11 39.216? DEC=-12 53 05.52
2. The mount had been powered on for approx 2 days again.
When the imaging run ended, the mount logs show a parking command was issue, but the mount did not slew to CWD. It just stayed in the same position and parked itself.
I unparked from the imaging software, and commanded park at CWD from Gemini driver and it did the same thing again.
I then went in to Gemini park settings, and configured the option to Slew to park at Az 180/Alt 31.82. before parking.
I ran the park command again and it indeed slewed this time to that position.. only difference being it wasn't exactly in the CWD position, but offset in Dec and
RA, so that it was pointing at that position to the south.
This is weird why it is forgetting how to park at CWD?
