Spawn pokémon (Pixelmon beta 12)

No pokemon spawn on land? We would need more information - including potential conflict plugins, like land protection. If you do not use anything of this, then have you checked in your to see if you have disabled mobs? If you have, then nothing would be spawning.

If you need further help, please join Pixelmon’s support team in our Discord.
