Current questions and answers regarding the map editor.

Is it possible to prevent certain creatures from spawning in a random stack? For example, I've set up a stack of random monsters, level 2, and I don't want spear throwers to spawn among them. Is there a way to implement this?

You can prohibit a faction from spawning in a random squad.
Assign a number, for example, 1, to the RacesRandomGroupID field.
In the map properties, find a property with a similar name, add 2 elements: 0 and 1, and in the 1st, add TOWN_FORTRESS to BannedRaces.
