So, i am making a custom map with 3 new custom races (and getting rid of the normal races) but building my second hero doesn't require the second town hall level like it should, i have put the correct town hall level in the "Techtree - Requirements - Tier 2/3" but it still doesn't work, these heroes were not based off of Tavern heroes but the base game heroes, (Paladin, Death Knight and Blood Mage)
