I have noticed that in one moment there are no enemies, and I can move my characters as I want to, and in the next moment Orks appear, and the last move done before they showed seems to count as if it had been made during combat.
That means that the character last moved before they showed up cannot be moved again, and is an easy target for them.

Also, when I tell a character to wait so that the next I click on can move first, waiting is all the character does during that combat turn. After reading the manual I had thought that a character who is told to wait would still be able to move during that turn.

Am I mistaken, or has that happened to you, too? It's very akward, is there any way to prevent this.
