Looks like you have a time machine and after reading my feedback you have have 
sneaked this exact change into patch 1/4! :-)

( The alternative interpretation is that i should start reading series at the 
  beginning - not in the most interesting looking (largest) places where i 
  would stupidly ask for changes you've put into 1/4 already. )
