Bows and crossbows that make their own ammo should not count THAC0 bonuses twice. slings that make their own ammo how ever are not affected. First video is before i installed 1.3 second is after 1.3 installed
in addition to THAC0 bonuses being counted twice if they have some special affect like Firetooth that bonus is counted twice. sorry for not showing that Firetooth doesn't have the double affect that the 1.3 Firetooth has.
i used the EE keeper to give my self the items though on my brothers computer where he hasn't used the EE Keeper it does the same thing he just didn't want to make a bug post
