When I press the Shoot hotkey, the monster is not directly in my line of fire. However, if I hold Shift and move the target 2 squares left, I get the image shown above. Then hitting Enter causes the game to say that I shoot, but the arrow never goes to the monster. I get no hit message and no miss message. I tried about 10 times in a row. It's perfectly consistent.
Occasionally I can see the missile graphic tile, 1 or 2 tiles away, but it's so fast/brief that it's a rare event. It seems to fire, but not to follow the path it's supposed to.
I'm fairly sure I've reported this in the distant past, but I can't find the old topic.
This ONLY happens with Shoot, not with spells. If I do the same thing with a Flame or Manathrust spell (before level 3), or with Stalactitic/Earthen Missiles, it'll hit, assuming the monster doesn't dodge.
