if you open any official BLizzard map, and try it from with in the map editor, and lets say you have made a Player change and you are Protoss, you will notice during the game that the 1.4.2 (even thought its properly installed) balance changes do not apply!!!
for example the tos upgrade shield is still 200/200 and not 150/150 as it should be!
have you noticed that? isnt this a bug? nobody reported on the official forums?
