spotting when turning around your units

[francoisD]

hi

i have notice that sometimes when you change the direction of one your unit towards one of the 6 sides of the hexagons, your unit can spot new ennemy unit it did not see in the previous ai's turn (and even in the same direction as it was originally facing).

is this normal?

can somebody explain this to me, and tell me where to find this in the manual?

since this does not cost any point of movement, could this be done automatically at the beginning of your turn?
because now i am doing this for every of my units and this does take quite a bit of (boring) time.

thanks!
