So I started a POC on Alpha Sapphire but I forgot that I had a mod that changed up the horde encounters and I don't want to delete it and then reinstall it. But most if not all of the pokemon I have access to are normally locked in poat game but thanks to the mod I have access to them early. So should I play as if they are locked in post game or should I evolve them even though I won't get credit for it on the pokedex? And here's the picture of all of the changes
