I fixed it, with the help of D803.(We PMed each other a lot) This was a while ago, but since you brought the topic back... In Multiplayer_Structure_Markers.xml, don't just add your faction's barracks(just using it as an example) to "Barracks", also add it to "Team_00_Barracks", "Team_01_Barracks", and "Team_02_Barracks". The same applies for all buildings. Now I have a new problem. I copied all the Hutt turret stuff, replaced all references to "Hutt" or "Hutts" in the duplicates with "CIS", and added the turrets in their right place for the CIS in GroundBuildablesSkirmish.XML. I can capture build pads, but not build on them. It's so annoying. :'(
