I've noticed an annoying bug when spectating a casted game in the client. It happens the majority of the time. When I choose to follow the caster's camera initially everything works fine. But if I ever change to "free camera" to go look at something myself, and then switch back to the caster's camera, I still see where the move the camera but nothing they click on will show up. Ie, if in free camera mode I had last clicked on some melee creep, then change back to the caster's camera and he clicks on a hero to check items, nothing happens. The Melee creep is still selected. Hope we can get this bug fixed!
