I gen a Munchlax with the moves Fissure, Metronome, tackle and recycle since Fissure comes up in Munchlax breeding moves. Fissure is pass down by Lapras. But it keeps coming up as error invalid relearn move 4: not an expected relearn move. Had that happen with other pokemon too, like Steelix. I been following bulbapedia for their move sets and breeding move sets as they have usually the right data for the pokemon.
Please help, I pulling my hair from this issue.
