Some of my units have different attack sounds, and they work fine, but I tried to make an attack fail sound for my recruit. It played the same sound as the normal failure sound when the recruit failed. I named it recruit_attack_fail.wav so I guess you just missed it. This probably also means you missed randomized fail sounds, like scourge whip_fail2.wav though I have not tested this. Other than that, I am loving the randomization and chance options. They give my Redwall maps new dimmensions. I’ll probably be releaseing a new version with more stuff for the TB 1.12 official release.
