I forgot to get the silph scope after defeat Giovanni in celadon (Team rock Hideout) and now there's a guard blocking the way in, and because of it i can't pogress to the pokemon tower in Lavender, i already searched for this problem at the forum and as i see, a mod need to teleport me to giovanni room again, is that right? if it is, can any mod do this for me?
