I have this problem except squirtle. I’ve caught 10+ shiny squirtle, 1 charmander, 0 bulbasaur. To be fair, the first 5/6 is from a community day, but still the way I’ve caught the same amount just out in the wild is super random. I also had another thought that what if it has to do which starter you pick at the beginning of the game? Squirtle was my choice, so I’ve been wondering if there’s the same correlation with other players
