I saw this in the Beta where an AI unit recruits Champions from 2 tiles away.  Was hoping it would have been fixed on release.

In my most recent game in [1.0], observed an opposing unit [Tarth] coming toward an available Champion who was 3 forest tiles out, so I placed my stack in front of him to block (Mountain on one side, Cave Bear on the other).  During the AI turn, the Champ was recruited and the AI scout was gone from visible range.  There's no way it could have ducked in, recruited, ducked out, then moved additional squares completely out of my Line of Sight.
