Both of these are needed for my hidden vs clout mod
A tag that allows a unit to stay cloaked while it's building or reclaiming. structures do it so i'm guessing it's not impossible. used for a cloaked 'thief' that reclaims enemy structures.
Shield LOD - hidden v clout adds a shield to every unit on one team - this places an incredible strain on the system with even 200 units on screen as i don't think the shields have any kind of LOD.
