I tested weapon-based combat arts, but to be honest, I really cannot say, whether changing the fightingdistance parameter changes anything or not. Is there any way to consistently reproduce the running-around-in-circles behaviour?
Why are the fighting distances in typification.txt changed, anyway? This should only apply to normal attacks, right? I would expect that only the fighting distances in spells.txt have any influence on the behaviour of the character while executing a weapon-based combat art. (Ranged weapons are a slight weakness in my theory, though, does the game use the maximum of the two fighting distances?)
