Not sure where to talk about this, but you can no longer go past the Cut bush on Route 16 to catch a Doduo. The western Snorlax has been moved up to block it and since Fly is now a Secret Technique, you likely can no longer get the TM for Fly to teach to your Flying type before Erika.

I also assume the game is gonna retcon the 50 tms thing to use SM's list of 100 like how FRLG changed to RS's list of 50 add some more somewhere.

The question now is, which is the game going to make you do first? Erika or the Celadon Rocket Hideout?
