Hi I was watching a few games and was always wondering why I see a dead creep or an totally different Hero Inventory when the caster is clicking to follow a hero.
Now I realzied, that this happens because the Dota Client doesn't realize that the caster selected a Hero over the Top Hero Bar.
The big problem there is, that the Unit last selected doesn't change even if the caster select an other Unit directly with the mouse. After that the only solution is to click "ESC", till the same problem starts all over again.
