command parameters are buggy.
for example @a[x=713,y=88,z=705,dx=4,dy=4,dz=6,ry=-135,rym=135,rx=35,rxm=-35] always find the player even if its position and rotation does not meet the conditions.
Tested on PC and there it worked so i'm pretty sure its a MCPE bug.

in MCPE 1.1 its broken even more because if I use any parameter (r, type, m) it says invalid syntax.
