I want to make a Berserker type upgrade for most units in an Altered Melee, but when I make the upgrade like they do for the Headhunter, both the Footman and (Footman 2 lets call it) appear. The Orc Barracks says it trains Berserkers, but they don't show until Berserker Upgrade is... Upgraded... I need some help doing this with other units. Thankyou.
