heck the 180 & 182 boxes in the "Flags" tab and visit Looker Bureau and Lysandre Labs (3F).

I actually created an account just to say thank you! I've been wondering about this all morning, I tried it and it worked. 
Thanks, bro!

Is the event 182 related to volcanion?

[ad75544]

Do i need to update my game? if so, to what version? my events 180 and 182 look completely different (182 was already activated)

[WhichOneForDiancie]

Which one is diancie

[Kaphotics]

Should be worth stating that it is not guaranteed to be flags at index 180/182. You change the named flags (the 16-digit number) per the picture in the first post, not "index 180". The index they appear at may be different for you.

I literally just made this account to ask if anyone had a different number for mewtwo cause it's not working for me.

Make sure you're at "Flags", and try searching via the "name" instead of "index".

Once you activated the flag make sure you send the save back to your Switch, then visit B3 of Lysandre's Lab.

What part of the story are you at right now?
