Butcher's Bridge attack move click

When i play the new Butcher's Bridge map, my attack move click acts weird. It often targets the wrong players (or minions). I haven't experienced this on either Summoners Rift or Howling Abyss. A friend of mine noticed this as well. Most others don't experience this, so it might have something to do with settings? I have tried it on another account (same settings), but no difference. Also, my fps is a bit lower on BB, but that was also the case with HA.

Great job though on this map, looks mint!
