My own experience is that BABIP is in fact broken in the new version for fictional leagues as well. I imagine the game engine will right it, but if the post here is a sign, any updates to individual player BABIP, or if you have mixed historical/fictional league, will result in any player with a game generated or added in BABIP rating being better than eight Jim Palmers.
