Sorry my English is not so good
I will try to explain the situation in a few words.
1; The Meridian Flip always works when I only use GOTO, which I tested several times a day and night.
2; The Meridian Flip never works, when I use the Align option with the solver.
3; Except this night he did the Meridian Flip correctly, the only difference to all tests before that all logs were turned off.
