Apparently this map has a bug, such that in game the top right two green creep camps are so close that the bottom one of those shows up as orange. This does not show in the editor for some reason, but it does in game and means that if you attack the top green camp the bottom one is also aggroed which has impact on the game.
I fixed it by adjusting the top green creep camp a tiny bit upwards.
Below are an image from the editor and one from in-game as well as the fixed map.
