Hi,

the item does get pushed into the array, but when you call 
Player#satchel again, the variable @satchel is reset to ['test']. So the 
previous array with the new item will be overwritten.

Check it:

player = Player.new 'testname'
player.satchel << 'testitem'
p player.instance_variable_get :@satchel
player.satchel  # this resets @satchel to ['test']
p player.instance_variable_get :@satchel

So you have to change those methods. This isn't good style, anyway, 
because a getter method is supposed to do nothing but get or calculate a 
certain value. It shouldn't change the object (except maybe caching of a 
calculated value). When you want to set default values, do it in the 
initialize method.
