starlancer I've had issues plate solving since the 3.0 beta. Last night I failed a meridian flip since it wouldn't re-solve
This sounds similar to my experience. The focus routine wasn't working and that messed up everything else.
After manually focusing, things slowly degraded as the temps dropped and the focus shifted.
I also noted that "Detect" never stopped trying to detect the star size once I'd pressed the tab. Even after a few exposures, which typically makes you run a new sequence for each exposure.
Were you able to run a focus routine?
