Custom Hero Limitage

I previously said in a thread that I was making a map with multiple race

I have run into another problem...

When a Hero is bought from a normal Altar the other blank out and require a Keep\Castle (in the humans case) but in my map that doesnt happen


i.e. - I click on Blood Elf Spirit Wayfarer and the icon disappears and all the Heroes are still avaliable without the next Town Hall (in this case Blood Elf Fort). I have changed the Tier 2 and Tier 3 Require ment to Blood Elf Fort and Blood Elf Bastion respectively but no dice

I need Help :<

Anyone throw in some suggestions plz.

I think you must edit the "techtree" gameplay constants and set your buildings by tier 2 and tier 3 and you must place you heroes in the list of heroes that you can also find in the gameplay constants.
