The thing is, after the movement animation, the units turn to the default map direction, that is, the map direction, and not to the position they were in before the movement.
You need to set the rotation angle; otherwise, it always defaults. I don't remember exactly where it's set, but it seems like this tab is called "Align" (or something like that).
And one more thing: how do you make a unit appear at the cutscene point itself, without the walking animation? It's very important. For example: in the third mission of the Necromancer campaign, "Lords of the Horde," after capturing the human city, a cutscene plays, at the end of which Arantir "raises" a zombie. How did the developers teleport the squad to that place?
They don't teleport them anywhere. It's the same Move animation, only with a negative start value. Set StartDelay to -40, and the character will instantly disappear or appear in the desired location.
In general, I advise you to explore the cutscenes from Nival; you can find a lot of interesting and useful things there.
