Weird warcraft bug?

Wtf, Try adding the mountain king searing arrows or frost arrows.
I havent tested it on other units or other autocast abilities, but after a few times that he attacks while its activated, his move speed stays the same however his running animation goes faster beyond any moutain king i have ever seen

I wonder if this is a warcraft bug, and if it is, has anyone experienced this before?

Arrow spells go to hell if they are given on melee units and they spell has a longer attack range than the given unit.

isnt that broodmother's ability in dota "spawn spiderlings" a dark arrow spell? and yet the brood mother is melee

It's not necessarily based off of Black Arrow; other abilities will spawn creatures off killing something, like the Orb of Darkness ability for example.

The only problem is the running animation, the rest works fine

so an animation going 300 times the speed it should is not "hell"?

meh, i hope there is some way to avoid this..

tried modifying the arrow spells range to be equil to that of a mele unit?

Try giving the melee unit a (very short, obviously) ranged attack.

its already melee range, exact range of his attacks.

blu that will just fuck things up i think, with his abilities and items since it wont be counted as melee.
