I get that problem about the Path of War tags all the time. In order to fix it, I move the following lines out of COM_3PPPack_PathOfWarEx - Tags.1st:
	
	
	
		
And copy them into COM_3PPPack_PathOfWar - Tags.1st. (note the absence of Ex) I don't know why this works, but I know it does.
				
			
		Code:
	
	  <!--The DarkFocus tag group is used to denote disciplines that have been selected by the Harbinger's Dark Focus ability-->
  <group id="DarkFocus" name="Dark Focus Disc." 
    inherit="Discipline">
  </group>
  
  <!--PoWFreeMan indicates that maneuvers from the tagged discipline can be readied without counting against the normal maneuver count (such as with the Harbinger capstone ability)-->
  <group id="PoWFreeMan" name="Free Maneuvers" 
    inherit="Discipline">
  </group>And copy them into COM_3PPPack_PathOfWar - Tags.1st. (note the absence of Ex) I don't know why this works, but I know it does.
