I don't mean  anything about the Pokémon itself, but for some reason Misdreavus does not spawn in the raid dungeon ,"???". I have spent a total of 10 hours trying to get the Pokémon to spawn but it does not.  Which can't just be a case of bad luck since it should have the same chance of encounter of 25, according to the  PBS across each four Pokémon. The strange thing is that I have encountered Misdreavus once, before I talked to the reporter after Roxanne.
