My first night with 2.4.2, guide stars dropped off one by one as I reported above. After going back to 2.4.1 that immediately resolved. Tonight I have had zero guide stars drop off the guide screen on 2.4.1. All 12 remain active or selected. Tonight I'm imaging the same target in nearly identical or slightly worse conditions Same time of night. All of the guide stars just stay selected.
Regarding the other issues people reported with 2.4.2:
I've had no PA issues with any version going back to 2.3.2. In fact, the other night I did an all sky PA on 2.4.2...then managed to kick my power cable...re-ran the all sky PA routine just to see and the final error from my alignment (25") was what it reported the second time! That was reassuring.
I have had no EAF issues.
Plate solve is a mixed bag. It was super fast on 2.4.2 for the hour or two I used it. With all of versions, sometimes it's quick, sometimes it takes forever. No rhyme or reason. Mostly it works for me using the new model/version.
No issues with WiFi. I always run in station mode. If I'm in the mountains imaging, I use the hotspot on my phone configured like my home WiFi and still use station mode.
I'm always on Android tablets running Android 15.
