    This looks very nice but i am also searching for it, i started 10 random maps and look in 20 normal maps no where too find. And in WOG option no new button for activat it.

    You must enable object replacement in WoG options for new buildings to appear. Did you read the description in mod manager?

      Unfortunately, I also tried, but I never found this building on the random map. I generated a lot of them, different sizes, settings, but Dragon Castle was never there. 3% is probably very little.

    I tryed that too already with enable and disable both dont work.
    Over F3 cheat Trainer i can get the Dragon ice and fire yes but i want that building where i can use fly too get too.

    I play that Game since 10years every week with 6 friends over Lan.
