I came back to Gearen City right when I got the choice to at the Secret Shore and when I went to Goldenwood Forest I walked back and forth from Route 1 -Forest Entrance which made me travel back in time to I believe Pre-destruction Goldenwood Forest (back at the beginning of the game) . It seems walking to Route 1 -Forest Entrance to Goldenwood Forest from the right makes it so that this occurs, while going in from the left side leaves the Forest in it's destroyed state (after the Gyarados event I think). It's not permanent, so you can pick which Goldenwood Forest to go into, but when you go into the cave in Goldenwood Forest Pre-destruction state and leave it the event plays where you get teleported by Melia back to the entrance of her father's lab. Perhaps there is glitches after the teleport, but I haven't tested it in-depthly.
Also apparently going to the Secret Shore to Gearen City means I am trapped in Gearen City and it's connected areas because there seems to be no boat back to the Secret Shore . Will pray someone can save edit me to safety or there is an update.
Edited this to specify leaving the cave and some grammar issues
