[1.04] Invisible creatures

[String]

1. Invisible creatures can be fished out & inspected using the context menu.
2. Invisible creatures are detected by auto explore (stopped thief northwest when I can't see him)
3. Auto melee targeting doesn't seem to discriminate against invisible enemies (as in it can automatically target them, even if you don't know they are there).


Alternatively could this be because my character did detect the invisible enemy but the game is not displaying the enemy as detected?
