"You must build a town hall.."

I'm making a custom melee game, but even though I set a custom building as a town hall (both in the building's settings and in the gameplay constants") the game still tells me to "build a town or hall or else be exposed to the enemy".

What to do? emote_sweat

U can try two ways:

Remove the "Force victory\defeat..." commend from the melee initliazation trigger. But if you choose this way you will have to make your own victory\defeat system

Edit the Great Hall\Necropolis\(...) and change them into "your" buildings. Everething shall be O.K.

have a look in gameplay constants.

I did. Read a little closer?
I'll try removing the standard melee triggers and adding my own.. Thanks, Vegeta.

Try putting a regular town hall in the "Dependency Equivalent" field of the custom halls. I think that does it.
