Just wanted to report that the Horns attack for the Bull NPC from the SWADE GM Guide is broken. Even though the NPC has a Fighting skill, it rolls as Unskilled. This issue can be fixed by copying the entry, unlocking it, going to the combat tab and opening the attack details, setting the attack type to ranged and then back to melee. This seems to get the sheet to recognize the Bull's fighting skill on your new copy. Since the original is read only, it can't be fixed directly in this way.

I didn't check every NPC, but I selected through a few at random and Bull is the only case of this I found.
