Update: fixed! Units not always moving on r-mouse down

If you're giving a command to move a unit a longer distance than their vision radius and you happen to click on an enemy unit that you can't currently see then nothing happens.

In engine/game/rts/guiRTSCtrl.cc in the collide function we need to add a clause for if we click a unit but we can't see it.

Adding in the else if clause here takes care of it

if (!unit || conn->isUnitVisible(unit))
      {
		 info.pos    = ri.point;
         info.obj    = ri.object;
         info.normal = ri.normal;
         //info.start  = event.pos;
         AssertFatal(info.obj, "GuiSquadTSCtrl::collide - client container returned non SceneObject");
         AssertFatal(info.obj->isClientObject(), "Non server object!");
      }

// new
 else if(unit && !conn->isUnitVisible(unit)){
       hit = gClientContainer.castRay(startPnt, endPnt, TerrainObjectType | StaticShapeObjectType, &ri);
   if(hit){
		info.pos    = ri.point;
        info.obj    = ri.object;
        info.normal = ri.normal;
        //info.start  = event.pos;
        AssertFatal(info.obj, "GuiSquadTSCtrl::collide - client container returned non SceneObject");
        AssertFatal(info.obj->isClientObject(), "Non server object!");
   }//if
  }//else if 
// end new

      else
         hit = false;
