I've had both of these abilities bug out on me by stating "not a valid target" even though I am targeting an enemy within range. I can sometimes pull off the attack if I target an empty square. But when all squares are occupied, I just have to pass that units action.

Also, sometimes my horse mounted ranged hero's animation for the AoE ranged special does not play and the game hangs for about 5-10 seconds until suddenly damage numbers pop up (no arrow tracers) and the round resumes. Other times, the animation does play immediately and you can see the arrow tracers. But the lag happens more often than not it seems.

On a side note, Bows are way underpowered for hero characters. They have no special ability like xbows, axes, hammers, swords and spears. All bows should come basic with the quick fire ability currently in place, 2 attacks at -20 accuracy. Beef up the current double attack skill to stack another attack every 3 levels or something. A hail of arrows in an area or a hail of arrows at a single target.
