as u can see i boxed 3 elements
u can see the "position" sprite is part of "boldPlayer" container, and "boldPlayer" is part of "Players" family.
dont you think the action should set the "GoToX" instance variable to the correct "position" sprite (which belongs to boldplayer container) X value?
if you dont then u havent read ur manual correctly.
and to prove that this is a slipped bug, when i replace the "players" object in the action with "boldplayer" object it works correctly, otherwise it assigns the x value of the first family member "position" to all family members.
