Last night EKOS was all set to do a Meridian Flip, but had to wait for my exposure to finish.  That was normal, and expected.
But my Nexdome didn't wait.  It moved to the new position immediately!   So that last exposure was ruined.
I had never seen this behavior before.

After the bad exposure was saved, the mount flipped as usual, and the dome was already move to the correct spot.
Everything else went as usual.
