I spent like an hour editing the kits of my favorite teams in the game, started a new game with the data editor change enabled, only to find out that I've wasted an hour on absolute nothing !! Kit mix editing does not work except for on the club information screen. 3D kits will remain crappy.
yeah! they really improve the editor. but next time they chould make it so it update any game you on. because it's a pain to always start a new game once you notice something you need to change. but yea!
