Hello. I hope you can help me. I accidentally evolved my larvitar to level 99, and I could only make myself pulp level 100, but my goal is to have a Tyranitar, but now I can not do this anymore and it took me a long time to get this pokemon. I ask that some moderator of the team please help me and return my poke to level 99 or simply evolve it to tyranitar
