Hoping someone can help me out here.
Last night I was imaging and everything was working good.
I fell asleep and the meridian flip went off around 12:15. After that it never resumed guiding. All the remaining images were lost because of this.
I have attached the log files if anyone would like to take a look. 

Thank you in advance.

Which version of NINA are you using and what is your scope/setup?

I am using the latest Beta as of last night. My scope is a 80mm refractor on an iOptron GEM45 on a pier.

Hi Jimmy

It appears your RA corrections went off in the wrong direction after the meridian flip. Perhaps you had "reverse direction after meridian flip" enabled either in PHD or maybe there's a setting in NINA for this?

Do you use greenswampserver or eqmod? GSS needs to have the reverse after meridian flip otherwise eqmod shouldn't.

Hi Byron

I looked more closely at your logs - If you did a meridian flip around midnight, the telescope is still reporting same side of pier, so that may be the issue if software external to PHD somehow thought it was on opposite side of pier and set something reversed. 

although that's a head scratcher because PHD still reports same side of pier
