So, like the title said, i was about to catch mew and when i tried to use an attack, the game crashed and when i logged back in, i was at the last pokecenter and lapras wa gone.Is there anything to be done?
Hi there, from the sound of it, it sounds like the game registered it as you killed Mew.
If you beat Nikola, who is located in Trainer Valley, you will get another chance to catch Mew. Careful though, Nikola is tough. Hope it helped.
