Moves canceled bug

Here some of my moves were canceled for no reason.
No, I did not pressed the end turn button and then forgot to press save.
Some of the moves, like those 6 infantry in northern Italy on the border with Austria that I brought from Rome or those in Lyon brought from Spain with an air trans were in between those which were canceled.
Also that attack on Berlin, I merged 1 inf from that town in Denmark with the rest of inf from Hamburg, but the final move, the attack, got canceled.

Anyone?

I have a similar problem, it's rather annoying I have no answer however.
