[Necrozma/Giratina]

I have all 4 Universal Fragments and I am clicking on the mirror that Gina is standing on (Both sides) and it isn't spawning either enemy.

[Game Pause]

Is there a way to keep the game running in the background? Or prevent it from pausing at the least? I'm not sure if that's an RPG Maker thing or what.

[Eevee]

Where are the Ice and Grass Rocks needed in order to evolve Eevee? I believe the Ice one is near where Articuno first appeared, but I have no idea on the Grass Rock.
