Thanks @geehalel - yes I tried what you suggested (manually issuing a goto for the same coordinates after the meridian had been passed) and the mount flipped. You're right that definitely seems a glitch on the mismatch between EKOS coordinates and mount driver coordinates (even when purged).

Do you think it is possible to fix this within EKOS? (For example through a routine that automatically issues a goto command - rather than a flip command - once the user-selected HA has passed beyond the celestial meridian. Sorry if that's naive, I'm not a programmer!). B/c otherwise this means that the user has to be physically around to manually issue a go-to command (which for example could be at 0200, 0300, 0400!) which would defeat the purpose of an automated imaging session software?

Thank you again for taking the time to help & explain.
