Ok I'm using Infested Kerrigan as one of the undead units in my map and unfortunately they continue to cloak as they attack the players' units, utterly annihilating them. I searched around and found something about disabling their doodad property but have no idea what that's talking about. I believe there was another way which involved detectors for the players around the entire map to just see the cloaked units...but I want them to not cloak at all and not turn transparent-ish, so I ruled that out already.

If it helps, I use StarEdit to make the basic map tile layouts and am learning my way through StarForge to edit everything else.

just go to player settings > special abilities and disable cloak for the player(s) owning the kerrigans

Or just always set 0 energy to all kerrigans.

Disable doodad state for infested kerrigan will probably crash the game, and even if it didn't it'll be permanently cloaked instead.
