I found it strange that the person who fixed the disappearing glow of Fury swords during the "stir" animation didn't fix the same bug during the joy animation. I'll post my fix in this thread.
Edit: Above, there was mention of a "mercenary camp" and a "fix for recruitable units." I'm not entirely sure what's meant, but if it's about the refugee camp and the missing alt-tier units and gnome/orc troops, then I made a fix for that (+a version for ВС, adding gnomes). Even if it's not that, it might still be useful to someone.
