Currently developing a mission using ALiVE as a means to generate a background conflict and general presence on the map while the user tackles a slew of side missions and the like. In order to implement side missions that are not frustratingly difficult to the player, I'd like the ability to have all factions withdraw units from a particular region of the battlefield for the duration of the side mission. Normally, I'd use something like a blacklist area, although I can't seem to find a way to enforce something like this dynamically while the mission is in progress. Any suggestions would be much appreciated!
