Current questions and answers regarding the map editor.

Oh, so you also need to storm castles? I'm having a hard time imagining how that's possible without a mod... Unless:
a) you create one unnecessary castle with empty walls, and leave the rest unchanged
b) when attacking it, you destroy the catapult with a combat script, and make the death model for it empty (destroyed – it disappears)
But I'm afraid it will turn out badly...
