I went full circle, loaded the default cold-n-dark (ADI had same issues) loaded with the ready for take-off (ADI was fine), reloaded the cold-n-dark and the ADI was fine. Seems as long as the engines are running the ADI loads just fine, if the engines are shutdown then the ADI does it funky thing.

Worse case I can restart the engines before saving my end flight so the aircraft loads with engines running next time then just shut down the engines. Not the best solution but better than loading multiple times.
