Okay, I've been on the latest beta of SGP since the "offset" feature went live. I've had good success with it, but it's really weird in getting started. If I try to start sequences with a Target that has "Center Now" selected, it will plate solve and fail to sync. Same as before the latest beta. I can try to resume, but it fails again. This has happened 2 nights in a row, and I don't know if it's just a coincidence or what, but it has worked properly on the third try both nights after I've clicked into the "Telescope" tab and deselected and reselected "Offset" in the sync behavior.
From then on, it plate solves and centers perfectly all night.
Weird!
Here's the log, first error occurs at 7:35 PM.
