Hello i am on johto journey and i moved on the Hallo Event map from Olivine City. And i start Catch pokes. The first think that i have seen is that you cant switch your pokes out of battle the 3rd put it first etc. so i moved to the poke center there i tried to use Bill's Pc (if they called like that) and i cant get pokes with kanto/Johto ID. ( I know that when you move to johto cant use Kanto pokes before beatting 8th Gym) so i tryed to pick johto pokes but they are locked.. And the last one is that when i catch pokes on that map have Kanto ID so i cant use them.
