I tryed to build parts of an adventure map and recognized a bug:
"scoreboard players set @a Test 0"
worked without problems but as i tryed to add things to the player:
"scoreboard players set @a[score_(dummy)_min=1] Test 1"
its not applying the score to all players with the value "dummy"
its setting the score "Test" for the player with the name "@a[score_(dummy)_min=1]" to 1.
pls tell me if you cant understand something and ill try to explain it again..

edit: the stuff behind the @a is in [] brackets it just turned into a link i dont know how to change this D:

edit: did further testing and it looks like it only aplyes for objectives containing brackets
