as the image, two of Knights Templar battles could do Conqueror without Gold requires.
both not conflict with each other.
first Conqueror medal Safed, you can keep all villagers until gathered all stone mine.
then all Villagers(also rescues from south, total 11 villagers) could be killed in final battle.
even the fortress only got lower than 65% hitpoints.
if you get gold medal later, but didn’t keep Villagers survive, you won’t get Gold medal and higher than 75% on the screen, it still showing Conqueror medal with 65% on the screen.
I tested.
I’m not sure it’s a Bug or official want to.
