I'm also having the bug, where it's not letting go to Route Nine.
Hmm, not sure if it is a bug or not. But I can't seem to quick save after visiting Greenhorn Island or Palm Island. Not sure what's up .
Yes, Meltan evolves. You can use a Metal Coat on it.
But where to find the metal coat
Could you tell me a litte more? When did this happen? If you could be specific I could check to see if it's a bug or not.
You can find the Metal Coat by playing in the Palm City Game Corner. It costs 5000 Coins.
