/execute @p ~ ~ ~ seed, outputs in commandblock instead of @p.

when typing

/execute @p ~ ~ ~ seed

in a commandblock and activating it.
outputs the seed in the commandblock itself instead on @p.
(see screenshot 1)
can also confirm if run at the player like

/execute @e[type=!Player] ~ ~ ~ seed

(screenshot 2)
this will return the seed to the player x times. where x is the amount of NON players around. instead of outputting it AT every mob.

when creating a score in the scoreboard
example:

/scoreboard objectives add randomNum dummy Number

/scoreboard players set Dinnerbone randomNum 9275

(in commandblock ->)

/execute @p ~ ~ ~ /scoreboard players list Dinnerbone

will output in commandblock aswell
(screenshot 3 & 4)

the /execute command is broken in many other ways aswell.
maybe spend a whole snapshot on this command!
